Thanks for the input Dave. I'm not terribly concerned about removing
too much of anything. If they made affordable units that would product
100% pure H2O I'd buy it. I intend to "regenerate" this filtered water
in one of two ways: Either by using Kent's RO Right and pH Stable to add
"stuff" back into the water (and to bring the KH/GH back up to "optimum"
levels) or by finding the right mix using RO/DI water & unsoftened tap
water. Maybe I need to do both.
Kent's R/O Right claims to be a brew of all the essential stuff. The
jar lists Sodium, Calcium, Magnesium, Potassium as well as "other Minor
& Major trace minerals". PH Stable says it contains carbonic acid
monosodium salts. Both claim to be Nitrate and Phosphate free.
I would think after using Kent's additives, Duplagan, Duplaplant, and
Duplaplant24 that I would have pretty fish/plant friendly aquarium water.
I lean towards this solution. This way I know (for the most part) what
I am adding to the water.
