Thanks for the tips. I have the 4 which I'm going to swap into my system this wkend, it's currently running in the sink with vinegar/rodi. My plan was to run it internally which is good as I've already found a couple leaks. The pump is very noisey, I was hoping it would quiet down as it breaks in, my IN-180 skimmer was the same way for the first few days. I'm not planning to use a pump to feed it, the calc reactor in my system now is running via syphon, so the plan is to use the same line already in place. I have a container of the coarse ARM and ZeoMag, Arm for the main and Mag for the secondary. I think I'm running my reactor with a target PH of 6.0, I'll have to confirm on my controller when I get home but it's working well now.
