Hi.
I've installed a water softener which uses a WAC resin and it does perform well at taking out alkalinity and hardness with it. As expected of water with no alkalinity, pH comes in the 3,5 - 5,5 range, which is standard for WAC resins.
So far I have used an standard concrete tank to store the water, only to find out that the concrete is probably reacting with the low pH water and is turning it both alkaline and hard, which is a huge letdown.
I'm planning to apply an epoxy coating to avoid this scenario of the concrete tank leaching calcium carbonate to the dealkalinized water, do you know of anyone intended for RO water or rainwater (since those also comes low on pH)? An epoxy for acids is probably overkill, but I do not want to run the risk of applying a standard coating for potable water only to find out it underperforms because "it is intended for neutral values of pH".
