Hi guys. This is my first post. I've been doing some searching and reading on TFP and can tell there is a wealth of knowledge and information here. Wish I had come 14 years ago. I usually have very little trouble with my pool. The possible exception being the pH going low. This year was a bit better after I learned that pointing my jets up would help rid the pool of CO2.
I covered (solid cover) the pool 5 days ago (10-10-2014) and had the water analyzed (TA:120; pH:6.8; TC:2.0; FC: 0.8). The pool store had me add 6 lbs of sodium carbonate and then 15 pounds of shock after six hours. I pull the cover back, pre-mix everything, and dump it into the pool. Everytime.
On the 11th they re-analyzed (TA:170; pH:7.0; TC:4.0; FC: 4.0). The pool store had me add 6 lbs of sodium carbonate (“pH increaser”).
On the 13th they re-analyzed (TA:185; pH:7.2; TC:3.0; FC: 3.0). The pool store had me add 6 lbs of sodium carbonate.
On the 14th they re-analyzed (TA:215; pH:7.3; TC:2.8; FC: 2.8). The pool store instructed me to keeping adding sodium carbonate.
18# of sodium carbonate moved my 30k pool from 6.8 to 7.3 and the plan is to add more…?
I suspect covering my pool while it had a chlorine demand and low pH before shocking has caused this problem. Comments? This weekend appears clear (no rain). I plan on peeling the cover back and letting the pool breath/ outgas .
Thanks for any feedback. Regardless of how brutal it may be.
