I've been procrastinating (as usual) putting in an iron removal system. I had a birm setup with air injection at the pressure tank and separate softener. The pressure tank got fouled with iron and the birm was way past it's lifespan. Ripped that out and put in a CSV a while back and just a softener with res-care dispenser. Works decent but get a small amount of bleed through with the iron and the H²S is sometimes annoying. I could probably get away with a regular AIO but I like the idea of that ozone sanitizing the media in case of IRB. I hear air will actually make IRB worse. I still have my old birm tank so really only need a valve and media. That's why I'm asking about valves. I know the clack valves rule but as a regular dude I can't get em. Any info or sources would be much appreciated. Thanks!
