Rated 4 out of 5 stars.
If you’re running a reef tank or sensitive freshwater setup, water purity is everything.
This Max Water mixed bed resin gives you 5 lbs of deionization media.
Drops TDS to zero fast.
Fits standard RO/DI canisters, model 104138-5.
Brand new, sealed.
When your resin changes color and your TDS creeps up, it’s time to swap.
This is the stuff.
No guessing, just pure H2O.
