green algea problem

[prego511]

I recently switched my 55 gallon tank to a 75 gallon tank with all new aragonite sand. After about three days the green algae started to build up. I can clean it off the glass and in no time its back! Now its growing on the rock and everywhere! I have a canister filter, a seaclone 100 protein skimmer, and 100 lbs of live rock. ph is 8.2 nitrates are 10 and ammonia is 0 I have one anemone, basslet, blenny, two clownfish, one coral banded shrimp, candycane coral, greenstar polyp, gorgonias, three feather dusters, one green button polyp, five turbo snails, 10 nassarius snails, four emerald crabs, some blue and red hermit crabs, and a sally light foot crab. All of the fish and corals seem to be doing great, but the algea is out of control! what can i do?

I would check my phosphate levels. where are you getting your water from? make sure the water your using doesnt already have phospahate or silicate levels.

I am using distilled water and have not tested for phosphates or silicates and dont have the means to do so. I have tested for nitrates and it has none. My other tank never had any algea problem. Could it be my protein skimmer isnt big enough?

I use to have a green algae problem in a fowlr tank but get my RO water from a different store now and i also put in one of those pad that absorbs phosphates , etc...
I also change 10 gallons a week on my 120. so thats 40% change per month which certainly helps maintain all my levels low.
