so i finally broke down and bought a ro
unit but the question i have is how is it possible to know if it doing what it should be ? im a little scared not to add prime just incase thier is still chlorine or what ever else is in tap water, where i live has a good water source and hasnt really given me any problems except a little algae and diatoms, should i start using one of those additives that prepare ro
water for use or is that just a load of it. i imagine ill have to use more calcium and alkalinity to bring up the hardness,i tryed asking the bigals guy if they had a tds
meter for sale and he didnt have a clue what i was talking about,im preaty shure he was a manager too.
