Main intention is to filter out chlorine, as it's not good for the microbes. It will be removing a lot of other nasty stuff too I dread to think about too.
If I filter the tap water for me because I don't trust what is in it, I should be doing it for the plants and biological potions too.
If you want a simple inline stainless tube, I could easily figure that out for you. I have a friend with a machine shop and I weld. How big do you want it to be?
Needs to be threaded. I will think it through and if I can't get it made locally I will get back to you, thanks.
Yup. A threaded cap with a 1/2" or 3/4" NPT fitting welded to it and another on the other side.
