The readings have been good.

I put 48 ozs. dry acid in and 9 ozs. cal hypo.
We now believe we have a leak but we're holding the chlorine and we don't have combined chlorine!!! We're losing more water than we should be losing to evaporation. We've spent the last week going over every inch of the liner trying to find a leak. We haven't been able to find it, but have found an area that the sand underneath has shifted, so we have an area to look at harder.
I haven't put anything else in until tonight because we are letting the water level drop to see how low it will go to see if the hole is in the bottom or on the walls. We had to cut the pump off when it dropped below the skimmer. I checked the water tonight.

Reesie,
I moved your question to the Construction and Repair section of the forum since this issue has nothing to do with the Baquacil forum. You can find your new thread here:

I no longer have combined chlorine. The chlorine demand has settled down. I've only been using 1.5-2 ppm a day for the last 10 days. I'm still battling high ph, though.

I just had to put 42 ozs. dry acid in to bring the ph down to 7.4
I'm having to put around 40 ozs. dry acid in every week to lower ph. Is this normal? I don't remember ever having to adjust the ph so often.

Drop your TA down to about 80 ppm and your pH will not be rising as fast. Also, muriatic acid is cheaper and more effectie than dry acid.

Okay, thanks, we'll try that.
