La Crosse Area Reef Keepers (LARK)
I am using a 6 stage RODI unit. I have tap water at about 350 or so. I have made about 25g of water and my color changing DI filling went from black to having 1/3 of it yellow. I know this is way too quick. What am I doing wrong?
I have about 65 psi and am using cold water
