Seen this many times in my buddies frag tank think was from egg crate only thing we can think of

Same happened to my frag tank not as sever as you as your describing, but try to keep calm and let the tank do its thing as I did and in time it will slowly go away and be completely covered in coralline algae, I call it new syndrome. But I was also running a 250w halide

i kinda thought the same thing as far as this being "NEW " even tho it is plummed into my main display ? but your saying just let it go and the algae will dissapear on its own ? i did have to scrape the walls and bottom but ive got a freakin ass wig growing on my loc-line !

NO3 at zero might mean it is zero because the algea is eating it up. Are you feeding the corals ? I worry about what I feed the corals/fish raising phospahtes --just guessing ou loud for yah.

Po4 levels?

Can also be a result of aged bulbs

yes i feed my corals .... reef chili twice a week and PO4 is .03-.07

bulbs over frag tank are all brand new

PO4 runs between .03-.07

You want to keep your PO4 no higher then .03, also do you have any clean up crew in your frag tank?

actually no clean up crew in frag tank .....

You need some, there is no natural predation going on, so algae grows freely, put few snails in there, depending on size of your frag tank small algae grazin fish. Even with levels colse to zero ( PO4,NO3), you will have algae slowly grow without algae eating fish and inverts. Just my .02 cents.

We were suspecting new egg crate leaching phosphates he switched to his old egg crate and priblem went away . We never proved it was just a thought his old egg crate was black also so maybe the white reflected the light more like the stuff in algae scrubbers u never see them use black right lol
