HOW LONG DOES IT LAST >>>SPECTRAPURE 90 GAL>TANK IS 240 WITH HALIDES.WHAT IS THE FIRST THING TO GO UP SILICATES OR PHOSPHATE?

Over all TDS will go up. I'd imagine a little of everything will be first to go up. How long they last depends on care of the equpiment and how often you use the thing. And if you flush the unit or not, lot's of variables. I think a year is kinda average, may wanna second opinion on that though.
