Phosban-Phosgaurd

[Canuckgod420]

I've used both phosban and Rowaphos and I found that they didnt really work the way I had hoped(maybe expecting too much?)
Now I use UltrapowerPhos by Fauna Marin and I am very impressed...it pulled my phosphate down very quickly and it hasnt changed.
I've had the same medium in my reactor for almost 3 months now and no rise in phosphate. It comes in a 1 litre tub and for my tank I only need to use 100ml...so its gonna last a while.

No first hand experience but there's also the concern of GFO with clams (here)
