Hey everyone, I’ve started to notice brown spots in my 10 G planted tank - it’s on certain plants, on the driftwood, the rocks and on the glass. Does anybody know what this is? And how to get rid of it? Infos about my 10 G planted tank: - Ammonia 0, Nitrite 0, Nitrate 5ppm - airstone running 24/7 - mostly Anubias and Java Ferns - couple rocks and a piece of driftwood - using liquid carbon (API Co2 booster) dosed 1ml everyday, and liquid fert (seachem Flourish) dosed 1ml twice a week. - lighting is 7.5 W - on for about 12h a day Thanks
My guess would be brown diatom algae. It may take a while, but it'll eventually consume all the silicates in the tank and die out itself. You can also manually remove, or get something like a nerite snail to help out a bit.
