Pink "Stuff"

[PoolDoc]

Just entered your pool info, and turned on your signature. I based the gallon calculation on 3.5' water depth, and on the break (transition to deep end) occurring 18' from the shallow end. Add 1200 gallons if it's actually 4' deep water.

Going back over the thread:

1. If you are going to drain and refill, do NOT add borates or phosphate removers until you have refilled.

2. Most likely 16,000 gallons of your water are in the top 3.5 feet. If you drain 3.5' of water, and refill, you'll probably lower your CYA from 130 to about 40 ppm.

Took additional measurements for pool size/gallons.
17 x 38 Grecian rectangular with 2.5 inward radius at each corner
3.5' deep at shallow end wall [SEW]
4.0' @ 8' from SEW
5.0' @ 16' from SEW
6.0' @ 21' from SEW
7.0' @ 25' from SEW
8.5' @ 34' from SEW [basically where drain is at]

What kits / strips are you using for YOUR testing?

What is the current status of the pink slime spots?

[djg9100]

Taylor 2006C test kit.
TDS + 500 per pool supply house. Does this affect the CYA reading in the test tube?

Pink slime has gone away for the most part. May get a small quarter sized spot occasionally.

Are you asking, does TDS level affect CYA reading? If so, the answer is no.

                 FC  T/CC CH   CYA    TA   PH   PHO
7/12-AM Store   1.0  1.0  260   60    80  7.6   100
7/12-AM Home    2.0  0.5  410  115   130  7.5     0

How is the pool store testing? Those numbers don't look like computer read numbers, but they are as inaccurate as computer testing.

As far as TDS/CYA, thanks, I wasn't sure.
Pool supply house uses drops for various tests, glass beaker with spinning capsule in it, etc. with computer printout of info. Pretty big diff in CH, CYA and TA. Going to check again tomorrow and double check results, but have gotten pretty consistent readings with my test kit.
