Bigger is better, slower pump speed to increase contact time.

Go to www.myreefcreations.com and you will find a 6" diamater by 24 inches tall that would be perfect for your setup. I have one of his fluidized reactors and the quality is top notch and very very reasonable prices. I think this model sells for $235.00. Pretty cheap compared to Deltec models which don't even meet the same build quality.

I second Andy's work at MRC.
I have had mine for over a year and it works like a champ.
I wish it was a twist off top instead of thumbscrews though.

Here is the webpage for the MRC reactors: http://www.myreefcreations.com/fmc.htm.

I would try to figure out how much granular ferric oxide (GFO) media you would need first. I believe that the recommended amount is 1 tablespoon (1/2 fluid ounce) of media for every 10 gallons of water you are filtering. For 700 gallons, you would need 35 fluid ounces (~1 quart) of media. If you plan to use PHOSaR HC, the recommended amount is 1 tablespoon for every 20 gallons or 17.5 ounces (~1 pint) for 700 gallons.

I have the smallest MRC FMC-415 reactor which holds about 3 pints of media. Since my system has about 100 gallons, I fill my reactor with 2 pints of granular activated carbon (GAC) and add several tablespoons of GFO. The GAC and GFO are separated by a sponge pad. For your 700 gallon system, you can use 2 pints of GFO in the FMC-415.

For my MRC FMC-415, I am using the Eheim 1046 (79 gph) pump and find it barely adequate. You may want the faster Eheim 1048 (158 gph) pump instead.

If someone thinks my calculations are off, please speak up!
