My light is on my work schedule. Lights go on at 7:30ish, off around 6-7pm. I have the tank light that came with aqurium, but natural light also comes in at certain parts of the day. At night, if I am gaming, my computer case also emits light into the tank. This light is an LED light, and I can change the colors at will.
Besides for my betta's own waste, I have no fertilizers and really don't know anything about it.
I occasionally breath at the tank when I feed my fish. That's it.
I got this bundle. The anubia is doing just fine, the Kleiner has brown spots and one leaf almost dead, the narrow leaf sword is losing it's chlorophyll I believe, and the amazon sword is brittle.
I have unpolished gravel for aquariums I bought a PetSmart. It's probably not great but from what others told me on this subreddit, it was supposed to be fine.
My temp is between 76-80 degrees, though it's been a bit higher lately because of the warmer weather.
I do a water change weekly, and have to wipe of brown algae from most of the leaves. Next month I'm going to get ghost shrimp to help with this issue, as someone in another thread suggested.
They come potted so you dont need a real substrate and they are a bit bigger so they can survive a bit.
Just make sure you clean and rinse them. Check a video on how to clean new plants.
