I have a question about my RO filter that I can't figure out.

The water going into the RO filter has a PH of 6.8 but when it comes out the PH is 4.7. Is this normal? Or is this because of all the calcium/lime that gets filtered out? Or do I have some bacteria in my filter causing the drop in PH?

The source is well water that has a ppm of like 700 going in and 0 after it goes thru the RO filter so the filter is working real good.

Anyone have any thoughts?

I have been adjusting the PH to 5.8 before using it as I store it in a 55 gallon plastic barrel and all has been fine but why the PH drops so low after going thru the RO filter seems weird to me.

I asked someone with some RO experience, and they said removing all those items definately lowers pH, hope that helps.

i was going to say the same. If ya want to get it to 6, just add back a touch of well water, till its at 6.......
