Do you ever see any bubbles in the incoming water? Ever get "air" trapped in the resin or other filters? I am not sure how to test for CO2 but I am pretty sure I have some in my incoming water depending on the season (well water). It came up in a discussion with Scott @ SpectraPure.
I luckily have no air in the incoming water, no bubbles in the DI resin too. I also have city water, the only thing bad about it is the low pressure.. I have to use a booster pump.
sounds like J probably nailed it. no way 7 months would run through a membrane with that tds. good luck with the search man.
Who knows.. I still won't complain as my reef is doing well and I have a ton of DI resin left. I will look into the city water's makeup and try to identify any red flags. Maybe it's more chlorine than usual... though I am not sure of that would do anything to the DI resin. Least my TDS is still zero.. even with the DI resin visibly half-spent.
