Media reactors.

[1bigstud]

I've recently increased the bio load in my tank. As such my nitrate and phosphate levels have gone up a bit. I can keep them in check with dilligence and water changes. However I will also be adding media reactors.
My tank is a 75 gallon reef.
33 gallon sump. Becket skimmer (great strong skimmer).
I was thinking of using bio pellets and phos ban, any other ideas, and suggestions where to aquire this stuff?
