Hi All, have had my tank set up just over a week now and am starting to get some hair algae mainly at the top of the tank on my redmoor wood and the back of the tank along the top should I be worried yet? I am following ed seeleys tutorial on the higher tech tank to spec barring the ada substrate I'm using eco complete. I have the lights on for the ten hours with the two hour blast of four tubes should I cut this down. Also I know I have a co2 issue as Ive used a full 600gm cylinder in just over a week I'm using a hydor turbo diffuser with a koralia 1 but a lot of it seems to head straight for the top and out. Any ideas would be gratefully recieved. Cheers Mark.
