Hi Tom,
I'm not using it right now because i'm testing some other additives, playing ginny pig with my tank. My last home tank is when i used it last, i used it for almost a year. I was dosing everyday though, or at least tried, sometimes forgot. I was only using this product, DT's and calcium additive. Everything was going really well (i moved since then and broke the tank down). It was mostly soft corals and LPS, but they seem to really open up more with the reef solution.
