You don’t have your own RO/DI system for that monster?? You gotta get on that
Thought about it, im using ati essentials pro...with that program water changes are optional. I was experimenting with a couple of parameters which is why i was buying water....as far as top off since owning the chiller...evaporation isn't an issue and im going 2.5 weeks through 5 gallons of water. I've been using distilled water with no issue.
