Can water be too hard?

I'm not sure if the water with too much CO3 can actually be bad or not; I don't think so but just want to make sure.

I let my dkh go and never care if its too high, I just keep up with calcium (hard job) and add baking soda liberally. My Calcium never seems to go past 420 no matter what my DKH is.

My DKH is 18-20... lol Is that a problem?

yes, your water can be to hard. Stop putting cement in your tank! How many times do I have to tell you that!!!!!!!!!!!

Yes, high alkalinity can wreck your calcium, pH, alk balance.

Rookie question... YES YOUR DkH IS WAY TOO HIGH!!!! Rookie!

Sometimes it slips to that range, but usually stable at 14-16dkh. My carbonates gets used faster than my calcium, so balanced or not i guess it works out.
