so i went to the fish sto today. got me water tested. amm-0 trites-0 trates-0:dance: still have some LR to add, but im cool. i took this pic to them and they said it is normal to have that brown crap grow on the sand. i didnt want to argue with him, so i went on my way. does it really dissapear on it's own? every time i turm on the lights, i spreads like fire. and also, whats the best way to bring you salt levels down, im a 1.028, just wondering. thanks to all.
