Well i finally took the leap and decided to purchase a 5 stage 75 GPD RO system for my brews. I have done some cost analysis and as much as i brew, it will have paid for itself fairly quickly. I went ahead and purchased the booster pump kit as well as my water supply will be feeding my brewery during clean-up and for other things. Any recommendations/tips & tricks for a noob? Looking for those little details that get left out from the manufacturer. I am really looking forward to dialing in mash pH as i know this has been a contributing factor in low mash efficiencies in the past. I plan on purchasing this pH meter. Any reviews from my fellow BA's regarding this meter? Thank you all in advance!
