Calcium deposits?

[halefmly]

Sandy and Richard,

Thank you both for the replies. I will use your suggestions to get the scale removed, and also to get the TA reduced.

I have been reading the thread with Ben's method for reducing TA. I have a spillover from the spa into the pool, and also a fountain water feature in the spa. Will those alone create enough bubble action for the outgassing, or should I run the spa's air pump as well?

Larry,

For fastest results, run the spa's air pump. The more aeration the better, unless you want to wait longer for the pH to rise (and TA to drop when you add acid). You should also make sure you get good mixing between your spa and pool water -- otherwise the pH rise, add acid, pH/TA drop process will happen much more in your spa instead of your pool.
