Hello everyone. I came across this site after my last run-in with the teenager at the pool store who was analyzing my pool water. I only resorted to their testing (and I use that term loosely) after my run in with the pool guy. I purchased a "distressed" home in January in Friendswood, TX and part of the distress was a neglected pool. I paid the pool company to clean it up, and even though it looks great, I can see some black algae spots now that I know what they are. Anyway, here is the equipment I have:

-19,000 gallon pool built in 2008.
-Intellichlor IC40 running on 80%
-Pentair Clean and Clear Plus 4 cartridge filter
-Pentair EasyTouch control panel

Here were my first test results from my Taylor kit this afternoon:

FC - 3 ppm
CC - I couldn't tell. The water turned a very slight pink color. I added 7 scoops (was using 25ml) and the slight pink never went clear. I stopped because the sample appeared to be supersaturated.
pH - 8
TA - 140-150 ppm (was light on 140 and dark on 150)
Calcium - 460 ppm
CYA - 35 ppm

The BBB method appeals to me because I have access to 18-20% sodium hypochochlorite for free. It's basically bleach before it gets watered down and bottled. I know I need to get my TA down and I need to do something about the black algae. Any advice will be much appreciated. Thank you.
