STILL having trouble with blue-green algae?
I have a male Betta fish in a 10 gallon tank that's heated to 80 degrees and filtered via a sponge filter. Awhile ago, I noticed some blue-green algae. I started doing a handful of things to try and control it without adding chemicals to the water.
I clean the filter every day in a bucket of the tank water. I do a 10% water change every day, and a 30% for the Saturday water change. I added an air stone to get more oxygen into the tank. I clean the cyanobacteria off of all the decorations every other day or so. I've cut back on feedings to every 2nd or 3rd day, to cut back on excess waste in the water. I added a couple apontogen bulbs to compete with the bacteria for nutrients in the water.
Problem is, the problem isn't getting any better. There's no improvement, and it's been about 2 weeks since I started fighting this. Any other suggestions? I'm at a loss.
I think the blue-green algae came in on a live plant I purchased. I've since removed the plant from the aquarium.
No, the tank is in the corner of a room, away from the window. The only light it gets is from the weak light on the hood.

Is your tank near the window? Any excessive light is going to promote crazy algae growth. My tank is in a room that gets a good amount of ambient light (plus the walls are white, so the room gets really bright) and that caused it to grow a fair amount of algae. I would also spot clean any algae that I see - you can use magnetic algae scrapers for that if you don't want to get your hand in the tank.
