I have a question for ChemGeek or anyone with chemistry knowledge.
I have a whole-house water conditioning system, and the water to fill my pool comes through this system. A few months ago I drained and refilled the pool (to get rid of high CYA), and all the fill water also passed through this whole-house water filter. This filter is not a traditional water softener that exchanges calcium for sodium. It uses a technology called "Template Assisted Crystallization" (TAC), which does not remove calcium and magnesium ions but causes them to clump together so as to reduce scale formation. Here is a link to the website describing the technology:

The filter also includes other stages for removing metals and other impurities as described here:

My question is whether this filter should affect my pool calcium hardness testing results, or the desirable calcium levels in my pool?
Today I did a test of my city water (using my Taylor pool testing kit) before and after it goes through my whole -house filter. Here are the results:
Test | Before filter | After filter
pH 7.0 7.4
TA 110 100
CH 170 120
Currently my pool water tests are as follows: FC=5.5, CC <0.5, pH=7.6, TA=100, CH=230, CYA=50.
I do not have a SWG, and I am using bleach and muriatic acid as my regular pool maintenance chemicals. I have not added any calcium products to the pool, except for one day when I added some calcium hypochlorite because I had run out of bleach.
I'm also wondering if my whole-house filter will tend to reduce scale formation in my pool, although I am trying to keep all the pool chemistry at the traditional proper values, and not relying on this filter to protect my pool.
