low PH-??

[fchaulk]

I read some last night and I turned on the Air exchanger and this morning the PH was up by .1 , maybe too much C02 in the room as Beverly suggested.

I do heat my RO water but I do not aerate it. I do check the PH before though and it always around 8.2 . I will try aerating it as well for my next water change.

Still have to do some more reading from Bev's water chemistry links as well. Did some last night , but a lot to understand in one go.

Thanks
