OTO and CYA and TC, oh my! What's being measured?

[aquarium]

Yep,

I understand the problem now. With aquariums the similar problem is with a slow build-up of nitrate, the end product of the ammonia cycle, which is diluted by water changes. So my thought was to apply that technique, albeit on a much larger scale.

I'm hoping that by starting with low CYA to begin with, that the rate of increase CYA>increase Cl>increase CYA can be held down to a flatter curve. Then smaller water changes to control the CYA level. We're about to go into dry season, so watering the yard with pool water gets double use of the water. The downside then becomes the higher use of muratic acid for the new water makeup. (EDIT: We already have high ALK, calcium and pH in the tapwater.)
