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.
