Please can you help me! I had a serious outbreak of hair algae. I thought I would be able to remove it by scrubbing the rocks. It got rid of the algae, but since then I have had seriously high nitrate levels and 4 of my fish have died. I have done two water changes in the mean time, but it has not helped. There seems to be brown algae now forming and i am not sure if its left over from the hair algae that has now died and is decomposing? Is this just a cycle it's going through and if so, how long will it last?
Please please, urgent help would be much appreciated!!!
