Did you happen to notice any alk consumption change when you stopped since you run an alkatronic? That seems to be about the most effective way we have in the hobby to indicate significant growth.I stopped using it almost a year ago. The doser lines started getting clogged frequently with salt crystals. I haven't noticed much of a difference since stopping it. I'm getting similar growth, PE and coloration with just phosphate dosing alone.
It also sucks that they dodged my questions about their internal data about how effective EasySPS was and never actually posted the "scientific studies" they stated they were going to.
