I have a 55 gal with some slow growing plants like anubius, swords and val. I use it as a grow out tanks for bettas. I have only 2 sponge filters and an airstone. the substrate is black sand.
at some point I saw blackish algae growing on the plant leaves but I did not know what it was as it did not look hair like. later I saw the hair but only on the sponge filter. I now believe it is black beard algae on the plants.
this will be a journal of how I try to get rid of it.
firstly, I have scraped off as much algae from the glass as I could and changed the water. I added some rams horn snails because that is what I have and some feeder/ghost shrimp.
results after 2 weeks. algae seems slightly less all around but only very slightly. some of the shrimp are black and some arent. this leads me tk believe some shrimp do eat the bba but nowhere near enough to make a diff. snails did nothing.
