Hey Shane,
I don't use a reactor, I find it works better/same running it passively in the sump in a cherry tomato bag
Currently I'm already running the Ultralith rocks with the ultralith system. Or did you mean use the Zeo rocks with the ultralith system to see if there was a difference?
I was using 4ml of coral snow daily in 100gal of water for the first week, then I decided to use it every second day. I read on zeovit that it was recommended 0.025ml/25gal 3x a week which is way less.
