i have always had phosphate problems with my tap water, it was the main reason I bought an RODI unit. Anyways my fresh batch of sw, mixed with rodi water, is still testing at 0.5 phosphate just like my tap water always did. Could it be the salt mix?
I am thinking about ordering new test kits, currently i use red sea, which test kits are preffered ?
