Algae issue's

[steiger33]

So I has a major algae break out of GHA and got that completely under control in my DT, my system is a 120 DT, 40g sump, and 65g all plumbed together.
Now I am having a brownish algae in the frag tank, and all over the frag plugs.
My parameters are
No 0
Po 0.025
Used NYOS test kits

Please help clear this up.

Also running UV sterilizer, skimmer, and carbon reactor in sump, ATO with Kalk.

I had same problem! I did lights off for three days and started running GFO, all gone one week later

I'm sorry I should of posted this was after lights out for 4 days and running phosphate rx. Which over the last 2 weeks dropped my phosphates from .25 to 0.025. Just weird that everything cleared up on the DT but the frag tank got worse.
