Hi, I have a 100 l planted aquarium that already had the cianobacteria algae problem. I added 250 mg Eritromicine per 100 l of water (without blackout of some days). I think the problem was solved, but now, after some plants added to aquarium and some weeks after, the problem came again. Now all plants have at least a "layer" of cianobacteria in all parts above the substrate. My question is: 1) Do you know any better medication to add to this aquarium to remove that bacteria? 2) Eritromicine again + blackout of one week would solve the problem? PS: I´ll anyway disassemble this aquarium because it will be set in another room, but i wouldn´t like to lose the plants. I´d first treat the plants and then move the aquarium. Thanks for your help!
