Many of the plants within our tank have started to develop a kind of algae (?) which looks a bit like blue fluff. We've done our best to pick off the affected leaves but it keeps developing and we're worried that it could be really serious and possibly harm the fish.
Can anyone tell me what it is/recommend treatments/tell me if it is dangerous for the fish??
Thanks in advance
