My wife, ever the chemist, says that vinegar will reduce aquarium Ph safely. Does anyone have any input about this? I've always used a commercial Ph reducer, but any time I can do something naturally as opposed to chemically, I'm all for it.
We live on an acreage, and so have well-water. It comes from an aquifer which runs through bedrock about 300' underground. The good news is, we'll never run out of water, and the water is naturally chemical free. The bad news: it has a standard Ph of about 7.6-7.8, so I like to reduce it to about 7.2 when I do partial water changes in my aquariums and indoor pond.It's acetic acid, so technically it would work, but I wouldn't say it's necessarily natural...for what reason do you want to change pH?
