I just upgraded from a single icecap 3k gyre to 2 Maxspect xf230’s. I am having a heck of a time figuring out the best settings. I tried OTC at 30% but I think it’s too much my BTA keeps moving and can’t seem to find a spot he is happy with. It’s a 90 gallon mixed reef tank. Right now I am trying 30% pulse for 10 seconds then it swaps to the other gyre and does the same.
