Ok, so as the title says on 6/29/2018 i pulled all the GFO out of my reactor, added a grow light and some cheato, and sat back to see any results. So, i did find that my cheap Amazon grow light can grow cheato like crazy! I am 4 months into this "experiment" and here are some other discoveries:
1. I do not have to chip GFO out of my reactor chamber every month!
2. I am using much less Alk solution than I have ever used despite having more corals!
I am just wondering if anyone else who has made this popular choice has noticed any similar results? It is almost as if the GFO was pulling Alk out of the water?
 
From what i've read it can cause calcium carbonate to precipitate. Thus needing more to be dosed.
