Granular Ferric Oxide ?

[CAPT PETE]

I wanted to get Rowaphos but noticed the GFO sold at Two Part Solution is cheaper. Are all Granular Ferric Oxide products the same? Meaning are Rowaphos, Phosban and the GFO sold at Two Part Solution the same product, just sold at a higher price?

Not necessarily. Usually the difference is in the size and shape of the granules making some work better than others. Some folks get along fine with the cheap stuff, others need the higher priced GFO in order to accomplish their goals.

The most effective carbons tended to be irregular in shape and offer a large surface area to volume. Here are some carbons to look into!!!

. ROX 0.8
. Warner Marine ReefPure GAC
. ELOS Carbon M
. TLF Hydrocarbon
