Bought four new bulbs for my 4 footer and since that my plants have grown really well but also my algae has taken off big time. My tank is fair to well planted with 40ish fish. Tetra's, platies, rasboras etc. I dose with TPN+ daily with 5ml, its a 200 litre/55 Gal with a EX1200 and C02 on constantly overnight through an inline diffuser on the outlet, drop checker running green to light green. My ammonia and nitrite levels are all zero and I do a 40-50% water change weekly. I did have a glosso carpet that is slowly turning into an algae carpet, my newly acquired moss has long lengths of hair algae all over it. I think its mainly staghorn and hair algae. With that amount of fish am I silly to dose TPN+ as it gives extra phosphate that low stocked tanks dont get but my tank is fairly well stocked so the fish give that extra phosphates etc that I don't need if TPN+ is adding them too. Am I better looking at TPN? or am I well wide of the mark?
