I meant to start a thread on my experiences, but I haven't gotten around to it yet... I've been dosing about a week and a half. Before I started, my Armor of God's had browned out, all except for one polyp. Three days after I started, the pink started to come back, five days in, they were brighter than they'd ever been. There are four new polyps starting to grow on it, the most that's grown in the whole time I've had the frag. All of my other zoanthids have been reproducing a lot faster, and their colors have been enhanced since starting, but the AoG's really took me by surprise...
In my softies tank, I noticed my pom-pom xenia has been splitting off like crazy since I started dosing.
My one system is a 75 display, 30 sump, and 70 frag tank - I dose 5/8 tsp 2x daily
My other system is a 30 display, 10 frag/fuge tank - I dose 1/8 tsp 2x daily
The only negatives I ran into were with my GSP and Yellow Sun Polyps. Both corals retracted about halfway for the first week, but the last few days, it seems like they've gotten used to it. You'll be emptying out your skimmer daily, because this stuff pulls out A LOT of skimmate. I am a believer in Vit-C, and will continue to dose until I tear down the tanks a long time from now.
