I was using it.......I now dose zeovit AA's and cant really say if they work any better as i liked the results of both...but I can say I like the fact that I dont have to dump capfuls of unknown crap into my tank....lol..just drops of unknown crap out of a dropper.......
I run high flow, low nutrient tanks and definitely see a benefit since I started in coral color and overall health. I only keep sps, polyps and a ricordia here and there so cant speak for anything else but it defintely helps all of the above in my circumstance anyway
