City or well for fill water

[PatL34]

The well water pH at 6.8 indicates some hydrogen sulfide gas. If you want to use it for adding or refilling without circulation, wait at least 6-8 hours before restarting circulation. As you don't have A SWC, the only problem I see is if there any metal parts in contact with the water. Samendolaro suggests using a PYROLOX iron filter, which I think is a great idea that I might try myself.

BTW could you also give us your CH and CYA values as well?

Well I'm now using city water for fill water since the TA of the well water is 300+. Using PoolDocs "HOWTO: Step-by-Step Guide to lowering your alkalinity" I've been able to bring my TA down to 240 from 300 in about 6 days. Is that about right time wise? I've got good areation going since I came up with a 45 degree adapter for my return on the pump and it's breaking the water surface nicely. Don't know how I'd do it without this forum.

Yes - that is good progress. Keep aerating.

Neither do we! We love this forum!

TA lowering process has went well. In less than 10 days I've lowered my TA from over 300 to 90. Tested today and TA was 90 and PH 7.4. I've been aerating 24 hours a day and have been dilegent in keeping PH 6.6 -6.8 during the process. Should I stop aerating now?

Hi Steven, welcome to the forum! Yes, it's time to stop aerating, if I remember correctly your liner prefers 80 - 120 so 90 is a safe place and your pH @ 7.4 is also in the mid range (I always like to have a little room for change it makes it easier to catch a potential problem before it becomes a real problem)
Congrats on the great results using Ben's methods, pool stores would have had you carting lots of acid and pH plus to your house and probably wouldn't have given you the excellent water you now have.
