Fast grower: Gatorade Zoa's, Duncan, and my Digitata
Slow Grower: Garf Bonsai, Spongodes ( this dude is a Hulk, no real growth but those polyps are everywhere), Blue Ridge Coral

I had a bit of a phosphate issue that I was stripping the Ca from the water. I just changed my GFO last week and everything is taking off again.
