Top Reddit reviews mentioning Swimming Pool Algaecides:
OP you need this product. Stick in your pump basket, but, skip the recharge kit and buy another one in 6 months. If you shock the pool with powdered chlorine, predissolve it thoroughly. Can cause a stain/shadow for a few days but fades eventually. This has cut chlorine consumption drastically. We were skeptical about carrying this product. But damn it works.
Get him to put out water feeders / birdbaths. Maybe with a bit of chlorine in it, supposedly like catnip, offer him a tablet. Needs to be closer than you are. This is best.
Warn him your pool has boric acid in it and its probably deadly to bees. Bioguard optimizer / proteam supreme are expensive versions of this. It also lowers surface tension so bugs cant land. They will find other sources. (A very useful pool chemical in a lot of ways, ph, algaecide, silky/sparkly )
All quats: benzyl ammonium chloride , polyquats: poly-xxx-ethylene dichloride, algacides even the cheap stuff (quats) reduces surface tension.

** Skill-it https://www.amazon.com/dp/B00AM3SHJ6/ is used for the same reason youll see half the reviews are for wasps, bees, bugs. Less needed - some apparently just spray the waterline. (May not be best prices for either) edit- added note on skill-it
I have struggled keeping my pool algae free for five years. I have poured enormous amounts of chemicals and shocked it so many times and nothing had worked. But this year I tried this product and boom it's crystal clean blue water. I have not seen a single patch of algae anywhere after 2 day of it being in the pool. Here is the link of the stuff on Amazon
Pool RX 101066 6 Month Algaecide... https://www.amazon.com/dp/B003UMOWWW?ref=ppx_pop_mob_ap_share I started the season with really bad Mustard Algae. I bought this from Amazon. (I have a 22,000 gal pool. They have different sizes for different pool sizes) Within a few days the mustard algae was gone, and it has stayed away since.
use this and you will never have algae again.
I know this and a few other pool subs are very against a product like this, but it works, and I have never experienced any of the side affects the pool purists suggest you will have.
its not all doom and gloom.
Try this.
It's foaming and has copper, so will raise metal in your pool slightly, but not enough to be problematic. Maybe test your metal levels afterwards and apply a dose of metal out if needed.
I was a first time, complete noob, pool owner when we bought our house (with AGP) last summer. Get a test kit, or strips at the very least, along with shock - either powdered or liquid, I use both (it was really hard to find last year so I bought whatever form I could find). Also get a chlorinator - the little thing that floats around that you put the chlorine pucks in. This year I added a poolRX to the pump basket and have had more stable water than I had all summer last year.
Pool RX has been a life saver for me.
I had water much like this after opening and initial shocks.. sadly not much changed until I did a half drain and refill. After that I was able to use https://www.amazon.com/dp/B01G2IYMKW?psc=1&ref=ppx_yo2_dt_b_product_details and it settled what was left in there and I was able to vaccum it up to waste.
good luck to you!
You need to brush with a stiffer bristle brush, but be careful on the liner.
Black algae spores have heads that need to be knocked off in order to really get to the roots.
After that, add this stuff:
The chemistry is fairly simple, buy some copper sulfate on Amazon, $4.99 for 5 pounds, and when you need it, say in the late spring, put 4 ounces in a pail with with some water, mix it to dissolve, walk around the pool and “sprinkle” it. We have a 10,000 gallon pool and this works, maybe three times a year. The treatment per year costs about $1 dollar, at least for us, and we are in South Central Florida. It works in conjunction with chlorine, so you have to keep an eye on chlorine levels, but that aside, it works, as suggested, very well. Your pool store will not recommend it, it kills their bottom line.
We had originally bought the finished product highlighted here, and it came in a nice flow-thru plastic container which we put into the water line flowing from the filter to the pool as recommended, and that worked. It was at that point that we started to think about the chemistry, why it worked. And, as noted above, we came to the solution of using the granular copper sulfate.
Go to the website for the copper sulfate and read the reviews, you’ll see that the majority are very favorable.

Put this in followed by a shock treatment. I've owned half a dozen pools and currently have a 25k gallon salt pool and a few ounces of that will fix it right up. https://smile.amazon.com/dp/B002WKO6U6/ref=cm_sw_r_cp_apa_i_t2ZmFbF4N5QV3
That looks like mustard algae, which can be a PAIN to get rid of. Green algae will typically die off with a good shock below 20ppm, but mustard algae can be resistant to a shock. So instead of throwing money at it in the form of chlorine and shock, check your local pool store for a "polyquat 60" product, or get it from Amazon. This stuff is specifically meant to kill mustard algae, and it works. I had a bloom last year I couldn't get rid of and made the mistake of wasting time and money shocking, and when that didn't work I found polyquats mentioned in my Taylor book (which I guess I should have read in the first place). Gave it a shot and within 2 days I think the mustard algae was gone.
Also, if you have the money, change your filter to a sand filter with a valve that allows for waste. It'll require less maintenance since all you need to do with a sand filter is backwash and rinse every now and then, and might even save you money in the long run depending on how often you need to change the filter cartridge.

This works really well. Make sure you shock, use your algaecide and proper filtration. I recommend a 36 hour treatment. Shock, use algaecide and use a wire brush on the mustard algae. After the first 12 hours of running your filter, shock it again. Shock a 3rd time at 24 hours, 4th at 36. After 36 hours, clean your filter out as best as you can.. another thing I’ll include is controlling your phosphates. Not a lot of people mention about phosphates but if you have surrounding trees/bushes that are getting into your pool, it’ll increase your phosphates, which is food for algae. Let me know if you need anymore help !
Edit: forgot to mention; Hasa Phos out works really well at reducing your phosphates. You should add this once the algae is gone.
So this combined with this other algae killer would probably be a good fight for the algae? Sometimes I’m out of town for work for 3-4 days at a time so if I can get something to keep the black algae at bay like these 2 then it would be worth it to me.
