I am currently working on this...Nitrates are 0, phosphates are 1, alk is 2.8, ph 8.2....I have a phosphate sponge ordered, should be here Saturday, I do not use flake food in this tank..it has seahorses, I feed mysis shrimp ( 1 cube in a.m. 1 in p.m.) which I have just currently started rinsing. I just added an airline, and a koralia 1 for flow, (may add more flow) and also am limiting my light. I have been siphoning out the algae as best I can too, and stopped adding all the extra nutrients I thought I was supposed to add.
Pic one is a diff tank, and that the new candy cane is in. I just got new MH lights, I think that is the problem there. I NEVER had any algae in my 225g before the MH lights. I did acclimate them too. I am getting a sponge for this tank too.
