I can definitely recommend phosgaurd as well. I used it in my tank. Went from extreme levels to none in a short time. And most importantly they have stayed down

Oh forgot Phosguard, now that's a good recommendation!

I agree about Phosguard. I have had better luck with it than GFO for multiple reasons. It will however lower phosphates to the point SPS/LPS loves it, but soft corals like mushrooms and Xenia might die back. Also watch your alk, especially with GFO. Move slowly as a phosphate reduction that is too rapid can catch some corals off guard, kind of.

Ideal phosphate is not 0 but not more than .03 ppm for all corals. I never use any of those media but I kept my phosphate level with just a good skimmer.

Had a question about your statement. First, you can keep phosphates at below .05ppm with just a protein skimmer? No fish? Wish I could do that.

Also, some corals do just fine at even above .2ppm or more. Yes, for best SPS coloration and best polyp extension in stoney corals that value is about .05ppm is accurate, but some soft corals do well with more.

The key word is "ideal" which means for most corals like sps and lps. The 0.05 ppm is the critical value. For soft corals you don't even have to worry about the phosphate level as long as you do your pwc religiously. We know that phosphate comes from anything you add in your tank which would be the fish food and additives. The answer to the question is yes I have a phosphate level of just within 0.03 ppm. You have to stay away from flakes. I sometimes have to shut off my skimmer for several days just to maintain my phosphate level. I feed pellets and may be frozen food once a week.

If you look @ a bag of cpe , you will see gold specs, thats the gfo & as you can tell its not very much of it. It is true that gfo works best in a media reactor but in my systems i have run it in a canister filter & top of a media basket with great success but that was in my system.

Now just be be clear, i run ff, purigen & cpe in my system daily but when a phosphate issue pops up i use gfo which i believe was the question asked, its getting late so i could be wrong, lol

I tried it on two separate occasions and didn't have much luck with either time but gfo fixed it within 24 hours, but that my system.

GFO crashed my alkalinity when I finally got it to fluidize in a reactor. Just watch out for that when using a significant amount.
