Question about Ph
Quick question about Ph. I have two aquariums, a 10 gal and a 30 gal. The 10 gal reads about 8.2, the 30 around 7.2. My water out of the faucet reads 7.8 or so. Why do I get 3 different readings off the same water? Both aquariums get their water from the same faucet. I use Prime as my dechlorinator.
