Re: Spring opening cloudy pool excessively high PH > 8.2
Hi PoolDoc,
03May2012
We've been struggling with the new test kit and wacky results; almost out of titrant and the CYA test chems. Long story for another time because i have many questions about all that testing.
For now, today Pete got the first good results and we need to know how to proceed.
Tonight our FC=4.0; CC=2.0.
(which is weird because 6 days ago we had FC=.4 and CC=3.0 and since CYA was 30, we did a shock treatment of 7.5 pounds Bioguard Dichlor to bring the FC to 30ppm and the CC to 0.0 - Four hours later the Taylor kit reported FC as either 2.0 or 3.6 and CC as either 20ppm or 7.6. Wacky results - so the next day we took a sample to The Great Escape and their results showed FC=0.4 & CC=7.4 - their Hardness=699, Alkalinity=ERR HI >250, pH=7.9, CYA=30. But the Taylor kit showed our pH was 7.2 the two times we tested the night before.)
So, I put in a 2 lb. bottle of Bioguard Easy Shock that same day. On Monday our pool wasn't so cloudy anymore, Pete bought 4 gallons Muratic acid and added only one gallon so far. Our test results tonight are:
- FC 4.0 ppm
- CC 2.0 ppm
- pH < 7.0 (took 21 drops to get correct color for base demand)
- TA = 210
- CH = 250
- CYA = 50
Our question is related to your previous instructions. (steps 4 & 5 from your 5:48am reply on 4/18)
You have the Borate adjustment listed before the reduction of Alkalinity. But since we need to get our pH to below 7.0 to lower our Alky, and that's exactly what it is right now, shoud we do step 5 first? And then when we do the borates thingy, the acid used will benefit that second part of your Alky instructions?
Also, we have no idea what you mean by "aerate" in step 5.
We'll wait to hear from you. Btw, the water is clear now and no longer cloudy. Just high Alky and wacky readings.
