AndreaW Posted April 21, 2022 Share Posted April 21, 2022 (edited) The past week I've been noticing a unique smell in my 10G Betta tank. It's almost an earthy-medicinal kind of smell. A couple days ago I noticed some larger bubbles accumulating on the water and a film between my water lettuce. So far it's only on the surface in one area, on the duckweed. I'm pretty sure this is the start of Cyanobacteria in my tank. Video: Is This Cyanobacteria This is my treatment plan: Start with a water change and remove as much Cyanobacteria as I can (remove the section of duckweed it's on, since that is the only area I can see it so far). Treat one full dose (1 packet/10G) of Maracyn Add more air to the tank while treating Wait one week before next water change It is my understanding that Maracyn will not affect my Nerite snails, or the BB, right? ETA: Also, I moved some of my water lettuce to the 46G Community tank. Should I remove all the water lettuce from that tank to be on the safe side, or is it too late? Betta Tank Parameters: Temp 79-80* pH 7.8 Ammonia: 0ppm Nitrites: 0ppm Nitrates: <5ppm Phosphates: .25ppm I add 2 pumps EG every week (probably should add more to get Nitrates higher) Edited April 30, 2022 by AndreaW 1 Link to comment Share on other sites More sharing options...
