So I have like, bright green algae in my cycled and divided 10 gallon. I've been removing it manually, making water changes, turning off the light during the day, and still it comes back in a bit. The betta don't seem to mind it! I tried to get a snail, but it died (I'm officially a snail-killer).
One of my bettas is extremely aggressive and will kill ANYTHING in his side of the tank. The other one is more docile but uh it's only a 10 gallon, and not much else could coexist in his half. So algae-eaters (and snails) are out.
Any other solutions?
