Alright, I have finally decided to post my test results after receiving my new K2006 test kit. I've had it for a couple of weeks, but wanted to make sure I was getting consistent results before posting them on here. I still have the brown stuff settling on the bottom of my pool every couple of days. (Vinyl Intex above ground, approx 5,000 gallons, Intex SWCG)
Test 1 (WEEK 1)
FC 2.6 ppm
CC 0.2 ppm
PH 7.2
TA 90 PPM
CH Test started Purple instead of red
CYA DOT did not disappear

I added 1/4 pound more of cyuranic acid and waited a week before testing again.
test 2
FC 2.5 PPM
CC 0 PPM
PH 7.2
TA 80 PPM
CH 50 ppm ?
CYA Dot still did not disappear but solution is at least blurry this time. I would guess it probably around 15 ppm.

Regarding the Calcium Hardness, I tried a couple of different things. Per the instructions of the K2006 kit, I tried adding 5 drops of titrant first to tie up the metals in the test sample then the buffer and indicator. Doing this the solution was blue before adding any more titrant. Then I tried adding only 3 drops of titrant to tie up the metals before starting the test. Doing this, the solution started red and I was able to conduct the test until the solution changed from red to blue. This way yielded 50 ppm, but I don't understand chemistry so this may not be acceptable at all. Some body please advise.

Since the CH test started out purple does this mean that I need something to take the metals out of my pool water? I have about another 1/4 pound of cyuranic acid. Should I go ahead and add all of this? I already have 3/4 pound in there now. The SWCG book originally told me to add 0.4 lbs which didn't even register with the test kit. One more thing, there have been a couple more sets of test results in which everything was pretty much identical to these. After adding the stabilizer, the TA seemed to drop, is this normal? How much baking soda / soda ash do I need to add to raise it?

Thanks in advance for any and all help.
