I paid Ward Labs in Omaha to test my water for my beer making (my secret shame) and it was listed as 9.4 there. No big deal for beermaking, but maybe not so good for fish. My tests even with the high pH test were the highest level, so I'm assuming the lab wasn't joking. I even looked at the water company website which gives daily readings of water quality, and it is always in the 9.3 - 9.5 pH range.How did you even determine that? Even my High Range pH test kit doesn't go that high.
Central Iowa. I'm thinking they artificially raise the pH at the water works as there may be some benefit (prevent leeching?)That's crazy. Where do you live?
I'll check it again tonight.Let it sit for 24 hours with some aeration and see what it ends up at.
They don't raise it that high .... usu. 7.8 or so is all that is needed to prevent corrosion in the pipes.
You might want to check the KH & GH. That would help to figure out what is in the water causing that high pH. You might also see if the water co. post water analysis results.
If the water is really bad, you will either have to go RO/DI (or a mix) or maybe find fish that really like hard water (like certain cichlids).
You want to get the other results - hardness, nitrates, phosphates .... etc. If they have limed the water to increase the pH, they might mention that as well. Also, some water co will post a detailed test (may be monthly) that shows the levels of all dissolved ions & solids.
Thanks for the note! I checked yesterday a.m. and the pH was down to around 8.0. I'll read the article now--thanks again for the reply!I got the report on line. According to them, the KH is 66, GH 149, NO3 is 10, and the only thing out of ordinary is high sulfates (60ish).
The water is basically relatively soft, and more than likely been treated with Ca(OH)2. The high pH is artificially raised & should be temporary. After equilibrating with atmospheric CO2, the pH should drop. <Likely to high 7's .... although the sulfates will mess that up a bit.> Try aerating the water for a couple days & see what you get .... you might be able to use the water after the aeration treatment.

The section in the middle - "soft water with high pH - talks about the effects of liming.
I live in a brand new development (2000+), and my house was built in 2004. Not sure what you mean by the last question. Are you asking about whether or not I can determine what water analysis from the water company is really the water that my house gets? I posted a lab analysis of my tap water in this thread, although I'm not sure it has all the info we need...I really think that the water's pH is raised on purpose by the treatment plants.How old is the area your house is in? Some old style under ground water mains can raise the pH but not usually that high unless the water going in from the municipal authority is high to start with. Does the water co. break down the supply grid into seperate readings?
I was looking at like 7.8 pH after 48 hours or so in the tank with filter running. The tank is a bit cloudy right now. No fish. Heat to 78 F. I don't mind getting this thing running slowly. I want to do it right!Sorry, could have been clearer. The reading at your tap is the one that counts. I know water systems have different parameters from point to point on the supply grid. A reading of the water going into the system is not a guarantee of what you will get out of it. You would not believe some of the stuff that happens. Was the pH 8.0 on the water you sat and/or aerated for 24 hrs?
