RODI resin for Texas well water

lapin · Jul 29, 2019

I moved this from equipment to chemistry in hopes someone knows

I have a friend who wants to start up a tank. They have a water well and are in the Austin Texas hill country. My question is if they go with a 3 resin system. C, A and mixed; What would be the resin that would be used up the quickest? We are thinking that we could use a 20" cartridge full of that resin so they do not have to change it out more often than the others. There will be some aeration to help with C02 but im sure that will be high as it is in most well water.
Cheers

I'll tag for the ride.

Has your friend pulled a test on the well water?

No test. We were hoping a fellow reefer might share some experience before we went all scientific and stuff.
This is from another thread we found here about the aquifier water. We are in the Edwards-Trinity but its pretty much the same we think.

Trinity Aquifier at 1000’ with a pH of 7.8 and TDS over 950.
