Water Well Question
Lenny, Limestone of course would be the cheapest to use to raise the hardness, but crushed coral would dissolve faster, followed by dolomite although I don’t know if these two are used commercially in such a hardening system. With crushed coral though, you would be able to use your water at a faster flow rate per hour, yet still get the same or better results as limestone at a slower flow rate.
Like you, I have never needed to use it as an in-line house unit with my plumbing (although I’ve used the crushed coral and dolomite in those tanks containing Rift Lake Cichlids to boost the hardness for them). It would seem that limestone would be easier to use and more conveniently obtained. I would also tend to think that if the unit is engineered to be large enough, using limestone would adequately harden the water at most any normal flow rates. Ray
