I have a 75 SPS only tank without a sump. All parameters are fine except I am noticing some color depletion due, I believe, to a rise in Phosphate. I run a seperate canister filter packed with carbon and want to now start running GFO. The question is, can I run both carbon and GFO in the same canister filter????? If not, I have a seperate canister I can rig up solely for GFO. How much GFO should I place in the cannister for a 75 gallon reef that has no sump????
Thanks mates
