Tank is slipping into algae hell - help

[WarDog]

At this point I would recommend you solicit some advice from G. Alexander on the Zeovit forum. Your case is very specific and I wouldn't want to give you the wrong advice.

You should not be running uv, gfo, or any aggressive carbon like ROX. Until you reach ULNS, you should only be using Start, Bak, sponge power and the stones. Nothing else.

Zeovit is a very finicky system, where changes should be made over weeks or months, not days. Plus, the use of dry rock is going to slow the process of reaching ULNS considerably.
