thx, weedhound. for the input.

i have pretty bad hardwater problems here. thats why there is a water softener in the loop, just simply need one around here.

but i was hoping with the addition of the softener i could get away with buying a smaller stage r/o system. sounds like your 2stage works just fine!

weedhound could you post me some specs of your tap water before it runs through the filter and after its been r/o'ed. like ph and tds? if not no prob.
