This stuff right here knocked out a persistent blanket of that crap completely in one treatment over a week and a half. Just be sure to add extra aeration such as a bubble stone while the majority of the blue green algae is dying/decomposing as it will raise your co2.
Try the advice that bquad gave and see if it helps. I've had battles with BGA as well and I am always on the losing side for some reason. My recent battle had me go and purchase this stuff from amazon: [link]
I followed the directions on the product and made no special changes to my tank and within a week the BGA was gone. From the comments this stuff doesn't contain Erythromycin.
Yeah that looks like blue-green algae. I've noticed both from the sub and also from personal experience that it tends to pop up and breed heavily in white sand, probably because light can penetrate further down into the sand and sand is fine so its good breeding ground for this type of bacteria. I treated it with this remover while having plants and shrimp: [link] It worked really well with killing the bacteria but after a while I ended up ditching the white sand because it would just come back in about 2-3 weeks every time I stopped treating it. If you want to still have a white covering, I would say to switch to a white gravel top and perhaps something underneath for the plants. Either way, I would say to simply switch the sand as best as you can and treat the aquarium once you put in the new gravel. I did this and never got that problem again.
Might be blue green algae, if so it's not an algae but a form of bacteria. You can tell by smelling it if it smells sulfurous/swampy. As well if you hold it to the light it should really be a very dark green. If these symptoms match I would recommend (this)[[link]] as it's helped me a lot with my problem.
Blue green algae aka cyanobacteria probably. Stuff can be a pain so get it early. Also large amount can deplete oxygen levels since it's a bacteria rather than algae. Peroxide can help sometimes. I've also had some success with
Yeah thats blue-green algae. Honestly, everytime I've used white sand I got blue green algae, I think its because the sand is white, so the sand "absorbs" the light, aka the light penetrates the sand further down and allows for a breeding ground of bacteria especially when using root tabs. I would scrap the white sand for either black sand for aquaruim plants or gravel. Once I did that I've never seen it appear again. I've also used Ultralife Blue-green algae remover on the white sand and it works pretty well, but I removed the sand in the end since it just kept returning anytime I stopped treating. The remover worked fine with my amano shrimp, betta, and guppies.
Here's the Amazon link for the Ultralife remover:
I used this blue green slime remover, one tiny scoop and the Cyanobacteria was completely gone within two days. I was skeptical of it before I got it and didn't see anything happening the first day, then came home from work the next day and there was no trace of it.
No issues with fish/shrimp/plants, though it's suggested to not use it frequently.
It's cyanobacteria, not an algae. I would manually remove as much as you can and then treat your tank.
Normally antibiotics is the recommended treatment to clear it, which also means it nukes your tank cycle.
I have also come across a product called Ultralife Blue Green Slime Remover which does not nuke your cycle. It doesn't use antibiotics but it does some form of oxidation killing the bacteria. I've only used it for a very mild case and it seemed to work. I don't know how well it would work vs a heavier case like yours.
I've read hydrogen peroxide may take care of it too, but too much of it can be harmful to tank inhabitants and can also nuke your cycle. I would consider it experimental and would require a ton of research first. The other 2 options are the safest.
I had a horrible outbreak of cyano a couple years ago and nothing I tried could stop it until I got this stuff. Cleared it up completely within a couple weeks and it hasn't been back since. [link]
I just treat it like an infection. It totally covered the floor of my 10 gal and kept coming back after numerous blackouts and removing all I could see. After 2 or 3 days it would come right back. This stuff knocked it out after one treatment and it hasn't come back a year later
PS: If you don't use an air pump already, add one during this process as the dying algae will spike your CO2 and could cause toxicity to fish
Buy this. It will eradicate the issue within a week or so. Only tip is to do one big clean prior to dosing, and then increase aeration with a bubbler during this time. I believe it's made up or different salts, so you don't have to worry about using meds or interference with your bio media.
Within days you'll see the traces of BGA wither away and die. Soo satisfying after a long battle of that garbage.
I've used this successfully to eradicate a terrible case of Cyanobacteria in a 20 gallon that was fully stocked with cherry shrimp, tetras and snails with ZERO casualties. Best money you'll ever spend, if you're tired of Cyano.
Do yourself a huge favor and use this. I successfully eradicated a terrible outbreak in a planted 20g with shrimps and snails present. 0 casualties. After a week or so the BGA simply dies off and you manually remove it without it coming back. It's a combination of salts to my knowledge, so no worries about crashing your cycle as erythromycin will potentially do. Only bit of advice is to do a water change and manually remove as much as you can prior to dosing, and increase aeration.
I’m new to having an aquarium so other posters may be better able to help, but I just recently had an issue with blue-green algae (cynobacteria). It’s hard for me to tell from your picture, but if you google Cyanobacteria in aquariums and it looks like what you have - I used this product, Ultralife Stain Remover off of Amazon.
It was gone in about four days, I dosed twice according to the packaging. Didn’t do anything else except a water change and slightly increased my water flow by removing some baffling in my filter.
Definitely give Ultralife a try. I had an outbreak in a couple tanks from new plants I hadn't cleaned well enough, and this stuff worked wonders for me.
Manually remove as much as you can, turn the air stone up, and order this:
Follow the directions and everything will be fine. I use it every time cyanobacteria gets out of hand in a tank and it is excellent.
I got a water pump like you suggested, I set it pretty low so it wouldn’t bother my betta too much but it looks like it’s doing the job! I think most of the Cyanobacteria is gone, I just have to syphon off the excess dead stuff and maybe dose the tank again to be safe. I used this stuff since it wouldn’t kill off my nitrifying bacteria.
I've had extensive experience dealing with cyano in my 20 long. The most effective solution for me was to use spot treat with Hydrogen Peroxide. Here's the rough process I used:
In my case, reducing ferts and light for a while helped outbreaks. Another option is to use commercially available product like this:
but I do not have personal experience with that particular product.
Have you cleaned you filter really well recently? I would suggest trying the blackout with lots of mechinical removal. If that doesn't work, my last resort was this which eradicated it from the aquarium. Be carefeul when using chemicals as it can have very adverse affects on your livestock.
Definitely cyanobacteria. I've heard this stuff works well [link]
But you should definitely keep the water extra clean. Maybe add some more low light plants to help soak up the nitrates.
Bro this stuff is actually a miracle, it completely destroyed my cyanobacteria problem. Now all if it turned back into regular green algae as god intended.
Instead of Flourish, I highly recommend looking into NilocG's All in one Fertilizer line. There are multiple variants, including one that is for low-tech and omits nitrates, called ThriveC. I'm going to assume that your ranchus make enough nitrates to the tank that you don't need to add more. Personally I never had luck with Flourish. All it did was grow algae but after I switched to the Thrive line, I never looked back. I use it in conjunction with dry fertilizer salts to help with costs. I have also seen Aquarium co-op's Easy Green All in One Fertilizer is a good choice, but that does include nitrates.
I still think that heavily covered leaf is a form of cyano bacteria. The red slime variant seems to be considered salt water but I've seen it in fresh water tanks. I've had something similar to it in my other freshwater 10 gallon tank before. I used a non antibiotic treatment and it seemed to have taken care of the problem for the most part. This product called Ultra Life Blue Green Slime remover is what I used. Supposedly it does it through some form of oxidation to kill off the cyano. I've also used it in a 29 gallon to treat a very minor case of traditional blue green variant of cyano and it took care of it. I don't know how well it works with a heavy, larger infestation.
As for the excess detritus, it's possible that there are dead zones in your tank where your filter isn't able to suck it up. Or you still need more filtration even though you have 2 filters. I know goldfish have a huge bio-load but I don't have any recent personal experience with them.
I used this - one treatment and it was all gone quickly. I put it in a tank with 3 fish, shrimp, and a snail and didn't seem to phase any of them. It's not an antibiotic so it didn't mess with my ammonia/nitrogen cycle either. The reviews are mixed. I put in slightly less than the directions called for, mixed with tank water first until completely dissolved, and then put it in near the filter outflow. Worked great and no harm done. I did a big water change 2 days later and put carbon in the filter for 24 hours. Like I said, though, the reviews are mixed.
If it traps bubbles it's cyanobacteria. In freshwater tanks it's more commonly known as blue green aglae.
This product will get rid of it fast:
This stuff got rid of it for me:
Ultralife Blue Green Slime Stain Remover [link]
Same. Worked great and even though the little bottle is like $15 you use so little so you will end up probably having it for years/decades if you only need to use it once every couple years or so.
The only thing I found is in the main tank I bought it for, while it got rid of the cyanobacteria, I then got a huge amount of a type of string/hair algae instead. However that stuff was a bit easier to remove manually than the slime algae it replaced.
Ummm I am not sure what I am looking at. Does it stink? You may have cyanobacteria. It is a photsynthetic bacteria not an algae, but behave fairly similar. A lot of people call it blue green algae. It happens when you have too many nutrients, light, and low flow. I had it once and I used the following method: I bought this blue-green slime remover and a UV sterilizer light to go in my filter compartment that I ran for a day or so. This completely cured this issue for me. It did not harm my snails or copepods.
Other options would be spraying it directly with H2O2 and/or glutaraldehyde (liquid CO2). The second method is more difficult and is more of a spot treatment. You can even dose the tank with both of these but youd need to do a lot and my dad killed most of his fish following direction of the dosing volume. However, this will work with black beard and staghorn algae as well which is what I use these products for. I use a syringe to squirt it onto the spots with the filter turned off and then do a water change. You can also spray with the water empty and then do another water change. This would not be good if you have livestock of course.
Hope this helps if this is what you have.

been having a problem with cyanobacteria for the past year in my 10 gallon tank. has anyone used Ultralife Blue Green Slime Stain Remover link: https://www.amazon.com/gp/product/B000QSK31M/ref=ox_sc_saved_title_1?smid=AKRJRDFZ5GQQ3&psc=1

UltraLife Blue Green Slime Stain Remover [link] worked wonders for a tank I have.
Looks like blue-green slime. This worked for me when i had blue green slime : Ultralife Blue Green Slime Stain Remover [link]
Ok this is going to be REALLY long and I apologize, but I've had a lot of experience with algae. Way too much experience, sadly.
Easy part first - the white stuff on the wood is normal. This almost always happens when new wood is put in a tank. It's some kind of harmless fungal growth. Just let it run its course, your critters might enjoy the snack while it's there, and in a few weeks it'll go away on its own.
The picture of the algae is a little fuzzy so it's hard to tell, but if it's regular grass green then yes, that's just regular algae. Unfortunately that's normal too, meaning you might not do anything wrong and it can still show up. It sounds like you're already keeping an eye on the food levels so that's good, keep making sure that you only feed your fish as much as they can eat in a few minutes and quickly clean up any leftovers. That's the most important step.
You can also try manual removal and cleaning (toothbrush might work well on those rocks) followed by a water change. It might be helpful to try a little more than 10% water change when you do that, as it kicks algae particles all over into the water. Might need to do it every week until the algae calms down. I've had success putting fine foam over my filter intake, letting it sit for a couple hours after the scrubbing, and then taking it out and rinsing very thoroughly. You can do that every couple days for as long as the algae is bad. Though I will say your algae bloom doesn't look that bad yet, in the grand scheme of algae growth.
If you have CO2 and natural plants, bump it up (safely) to increase their growth. Some people have great success squirting liquid CO2 (Flourish Excell) right onto the algae every few days, although that never worked for me personally. Live plants are the safest, easiest way to use up the excess nutrients that cause algae. Even if your phosphates are low, there are plenty of other factors that can cause algae to get ahead. If you don't have any live plants and aren't sure about getting some, though I highly recommend you do since they're one of the best long-term solutions, try getting a bunch of floating plants in the meantime. They use up so much nutrients and they're extremely easy to keep alive.
Other things too try: less light - set your timer to no more than 6 hours. I've done as little as 4, with a 4 hour dark break in the middle of the day (which is supposed to starve algae) when I had a particularly stubborn outbreak. If natural light hits the tank, try to minimize it. I've found that sun causes algae faster than any lightbulb. If the algae gets really really bad, which it doesn't appear to be yet, you can try a manual removal and water change, and then a blackout for 3 days. Turn off its light and cover it with a dark blanket for 3 days.
Also, if you don't have algae cleaners in your tank and you are able to safely stock more, definitely consider getting some. Dwarf suckers, bristlenose plecos, etc. Also amano shrimp or even cherry shrimp, nerite snails, and mystery snails. Let me tell you, my tank was never cleaner than when I had a bunch of nerites. I quite literally never had to scrub the glass. I know snails should be ok, but you'd have to look up what gets along with tetras because I don't know much about them.
This last bit is important though. It is possible it's blue-green algae though, but again I can't really tell from the picture. It's more of a vivid blue-green color. It's actually a bacteria called cyanobacteria. That stuff is a huge pain and extremely aggressive and the treatments for algae won't really work on it. It's hard to find treatments for it for freshwater but I did find one that I've had great success with the one or two times I got cyanobacteria. It's called UltraLife Blue-green Slime Stain Remover. It'll say in the fine print on the box that it's for freshwater, not to be confused with their similar product for saltwater. Don't know if links are allowed but here it is.
Its blue-green algae. I use this stuff. Works really well and it's safe for all the animals and plants in your aquarium.
Blue Green Slime Remover took care of it in both my aquariums within 2 days each time. Never came back after treatment.
There's a really good blue green algae treatment on Amazon. It's worked every time I've used it and hasn't harmed anything I have in the tanks.
My best advice is to read through this article to verify it is in fact Cyanobacteria. If so, address the root of the problem, which could be dirty gravel or filtration (possibly need more filtration or increased flow). I neglected a 20 gallon long in the past, and I completely cleared up Cyanobacteria in that aquarium by doing a thorough vacuum, and dosing a product by Ultralife (I increased aeration and followed directions). No fish or plants were harmed in dosing. Here's the link-
Try this stuff for the BGA, it works like a charm.

This. Worked great for me. Didn't harm plants.
This was recommended to me:
I just started using today so we'll see if it works in a week.
Edit: Loooove the moss by the way. Really pretty tank!
Yeah sounds like cyano. Ive used Ultralife Blue Green Slime Stain Remover [link] before with decent results. Make sure you add and air stone during treatment.
I am not using spirulina , going to try this stuff before dosing with erythromycin as I heard erythromycin kills your biological bed
Get this stuff works amazing! Ultralife Blue Green Slime Stain Remover [link]
I noticed that cleaning my filter, coupled with this product did the trick:
