Phosban Reactor Question

Steve9877 · 03/24/2006, 06:42 AM

I am about to install a Phosban Reactor in an attempt to starve out some stubborn microalgae. My system is about 150 Gal. total volume. According to the directions on the Phosban media container I should use 150 grams for 150 Gal of water. Instead of this ammount I was wanting to start treatment with a much smaller ammount of media per Randys artical on the use of this type media.
My question is, the directions on the reactor say use with a minimun of 130 grams media. Will the reactor not work properly with less than 130 grams of media? That doesnt make sense to me. Do any of you use smaller ammounts of media without experiencing problems with fluidization, media grinding etc?
I really dont want to risk stressing my corals by dropping the phosphate levels too quickly. I wouldnt have bought the reactor had I known I couldnt use small ammounts of media if desired.

Good plan.

I've not used an actual Phosban reactor, so I cannot say what happens with less, but I think that others have used less. I have typically used a cannister filter when experimenting with GFO.

Anyone want to chime in?

Reduce the flow going into the reactor and you will be fine. I have a 180g tank and the PhosReactor and use about 3-4 teaspoons in my reactor. I use the overflow pipe as a feed into the reactor so I can't tell you how many gph that is.
