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?
