This is a 33 gallon tank with river sand as substrate. I have good lighting that stays on for 8 hours and its near a window which gets strong sunlight for about 3 hours. I have low Co2 consuming plants in there so I don't use CO2 and just do partial water changes every 2 days. The tank was set up 2 months ago. There blue opaline gourami fry in there and a few pond snails. I have a very small biofilter in there.
There is some green stuff on the driftwood so I suspect the water is cloudy because of green algae. Is it blue green algae and is it harmful to my fry and plants?
