Becoming a first-time kalk user. Help!

All seawater is poised to precipitate calcium carbonate. Limewater will tend to boost this process by raising the pH.

There's certainly no problem with low dosing limewater from a reservoir, but a reactor might be hard to control the actual dose. A stirrer on a timer might be able to do it.

So if I put the stirrer on a timer and controlled dosing by keeping pH in check with my Apex I should be okay even if my demand is low and water changes are few?

You can't judge the needed dose by pH.
