Chemipure Green In reef with refugium?

[Sam Hodge]

So I recently acquired a new 29 gallon reef tank, it has a HOB refugium that works pretty efficiently, however the tank was neglected before I got it. I decided to add a aqua clear 110 with filter floss to take care of particulate. While setting it up it occurred to me there was a good way of filtering out any chemical warfare that would be going on in the tank. I didn’t want to add plain carbon but I didn’t want anything like Chemipure blue that would take away from what the refugium is already taking care of either. So I was thinking chemipure green. It still has a really dense high grade carbon that would take out chemical warfare produced by coral but it wouldn’t have any GFO to remove phosphates the refugium needs. Thoughts?

Yes its a good idea to use carbon instead of gfo otherwise youll be low on po4 and high on no3 and your macroalgae wont be able to reduce no3 when po4 runs out! So no gfo.
