Please can I have some advise as to what I need to do to overcome the BBA that I have in my tank. Just to give you some background,this is my first tank and I finished cycling it about two months ago. Tank Spec: 65L Lighting: 2x11WPL on for about 7 hrs daily CO2: None Filtration: Inhood wet / dry trickle system Fertilisation: ProFito 10ml weekly. EasyCarbo 5ml daily and EasyNitro 10ml daily. Plants: Camboda Vallis Anubais Various Fish: Corydoras Julli x 4 Harlequin Rasboras x 8 The Camboda is looking very healthy and bushy, Vallis is going a little transparent in places otherwise looks okay. The anubais do have dark algae on the leaves but are growing new leaves. I did have an outbreak of Cyanobacteria which I think started in the substrate at the front of the tank and then spread fairly rapidly. I did a complete blackout of the tank for three days and thankfully it cleared. I was advised to increase circulation in the tank so I purchased a Koralia 1 about three weeks ago. Now I am sure I have BBA. I have not increased the dosing of EasyCarbo/EasyNitro as I'm not sure how much more I can add before it becomes toxic to my fish. I also carry out 20% water changes weekly.The algae is on the 3D background, some plants and a little on the bogwood. Any advise would be very welcome, and thanks in advance.
