ok, well I have my CYA at 55 and I've stabilized my FC level where I'm keeping between 7-10 for the most part. I had order some calcium chloride to fix my CH problem since it was at 180 and I have a pebble finish pool. I was surprised the CH remained steady at 180 even after replacing quite bit of water. So I tested my tap water and it was reading 120. Out of curiosity I looked up the what the Leander city water report was and it showed 210 Ca/Mg hardness for 2015 the latest report. '10-'14 showed between 165-189. So I guess the numbers probably make sense.
So back to fixing the problem. I ordered a 25lb tub of Calcium Chloride. This is huge, but by my calculations on pool math I need to add the whole thing. To go from 180 -> 300 pool math tells me 352 oz or 22 lbs. The tub says to raise a 20,000 gallon pool 100ppm add 25lbs. So I was going to add half test then add 2nd half test.
Questions:
1) Am I off on anything I said above?
2) Any special instructions on how to add? It just says to spread across surface. Do I grab a scoop and just start tossing it across the pool?
TIA for any suggestions.
