Hey All its been a while! I'm looking to add GFO to my tank. I'd like to lower the phosphates in my tank since I feed heavily. I wanted to get some feed back from people who have more experience than me. Bouncing a couple ideas around. 1. "tee" off my return pump to feed the reactor or 2. Get a unit with already a pump. Please I'm a newbie with this equipment so point out the obvious as well. One thing I do know is, GFO media should not move around like bio pellets... BTW any good recommendation on a brand of GFO reactor. One that can hang in my sump next to the skimmer would be nice.
