tolstoy21 Posted March 16, 2022 Share Posted March 16, 2022 (edited) Cause I'm anal and get fixated on the little things, I rigged up the below to dial in the water hardness to my aquariums (to both my breeding setup and display tanks -- all are on AWC). In the below I plumbed in a water softener cartridge with a bypass + gate valve. The gate valve allows me dial in the amount of 'hard' water that bypasses the filter. Since installing this, my water went from around 250ppm hardness to somewhere in the range of 50ppm according to the COOP test strips. Going to test with API drop kit as soon as I get one just to have a couple different reads, then I may tweak the hardness a bit. Why am I doing this? Well aside from being crazy and liking to tinker with things, my well water has a kind of funky makeup. Kh hovers just above 0, GH is around 250ppm-ish, and nitrates are 40ppm. I keep pretty much all soft-water species (tetras, apistos, etc) so I wanted to tinker with lowering their GH. The recharge port shown on the right-hand side of the picture allows me to manually recharge all the resin with a brine wash, so I don't have to continually replace any of the filters which would be more of an expense than I'd ever want to incur long-term. This basically allows me to do a semi-automated regen-cycle. I've been running de-nitrate filters a few years now, so the GH filter is a new addition to an existing, working system.
