Edit: for the price, if it actually does everything AquaticLife claims it will do, then it is bargain. It self flushes the system prior to each start up. It monitors pressure and makes adjustment as needed. It has a safety device and automatic cut off as needed. So, here’s hoping it actually works as promised.Last minute purchase to raise my pressure for the RoDI unit. Will post when I evaluate it and see how it does. So far so good.
