    Just to clarify, GAC, or carbon, has no control over phosphates. GFO, granular ferric oxide does. Carbon takes some toxins and organic carbons out.

    Thanks! I had no idea the green was coralline. No idea how it got in there. The cyano is a pain. Most of it is gone, but now i'm dealing with a new type of algae -_-

    Just so I'm not pointing you in the wrong direction, if you can rub your finger over the rock and it's tough and smooth, it's probably coralline. If it wipes away easily or is very hairy, it's nuisance algae. If it's the hairy type, get yourself a clean up crew of snails and hermits and they will eat the stuff up. Just wanted to clarify cause after looking closer to the green pic it looks sort of hairy. But still, nothing to harmful with the right CUC.

    It's soft and didnt rub off easily! So I guess it was on a snail's shell and now I got it.

    I recently changed from GAC to Magnavor Pura. So far I like it. It contains both GAC and GFO. I've always had a tiny trace of Phosphates, but now there is none at all. I use it in bags, but I'd imagine it would work really well in a reactor.
