Okay, i guess RO is the best, no question. Has any one tried "Tap Water Filter" by aquarium pharmaceuticals??? I have attached a copy of my town water report, i cannot make heads or tails of it. Is it good or bad or middle of the road??? so.........do i spring for the RO unit (which type i have no idea), use the tap water filter or just plain tap water. I have a reef with soft corals and fish,
