I hope there is a better options than replacement. :rant: My CH is 620!

Miscalculated CH test at opening and added too much calcium. :hammer:

Is there ANY solution other than draining water to get my CH down? Please!

The only other option I have read about is lowering TA and watching your ph closely. Personally I would drain 50 percent water and replace.

Agreed; you can manage water that high by keeping low pH/TA, but I wouldn't do it unless I had no choice. I presume your fill water isn't too hard in Virginia?

There are three approaches.
1) Leave CH high and lower PH and TA to compensate. This approach is the easiest to start doing, but it has risks. If you let your PH get away from you even once and it goes too high, there can be calcium scaling. Over time the CH level will come down as water gets splashed out, overflows, or is otherwise replaced.
2) Replace water to get your CH level down.
3) Get a reverse osmosis treatment to lower the CH level (and all your other levels).

Replacing water is going to be your best choice in most cases.

I don't know about CalTreat in particular, but many similar products have all failed to work.

You can use sequestrant to minimize the chances of scale forming, but that can get expensive.
