Gfo?
Should i run GFO in a brand new sps tank?
I heard some negatives about this stuff, therefore, i ask? I will also be dosing microbacter7.. I want to stay away from the vodka dosing though. |

Agree with Fish_wiz2, I would only run GFO if your phospates are elevated. IME corals react the best when no GFO is used and phosphates are minimal.

I disagree with those above. If you have fish and feed them, then you have phosphates in the water. If you don't bind some of those phosphates with GFO, then green hair algae and bryopsis will gladly do the job for you and that will happen long before you get a positive result on your test kit.
GFO isn't going to harm corals if used in small amounts, for example start with 1/4 of recommended and add more as needed. Rise the media well so that it doesn't put particulates into your water that will irritate corals. GFO is no substitute for good husbandry (i.e. regular water changes and not overfeeding).

Vodka dosing is quite amazing and alot cheaper than GFO. Just read all you can about it. Its nothing to be scared of if you pay attention to what your doing and are patient. Melev has about one of the best write ups I have seen to date on vodka. Its on his website.
If not vodka then yes I would run GFO. Especially if you have any phosphates showing on your test kits.

Your rock didn't cycle? It was dry rock created from materials that were phosphate free to begin with? No dry, dying, or decaying mater?In short, yes you likely have phosphate, potentially high actually. I would let the tank cycle with the rock, stick in 1-2x the amount of GFO recommended and let it run for a week (again, safe since the tank is empty of fish/corals/etc, nothing to "shock"), then replace it with a smaller dose of GFO used to regulate your ongoing phosphate additions to the tank (i.e. food).
