I have set up a tank that was given to me by a friend of mine. I have added some plants and some fish and am waiting for the tank to cycle. I have some experience with plants and fish, but it has been 10 years since I got to play in the water and I have forgotten much.
I live in south central Indiana (near Bloomington) and was always under the assumption that our water was "hard". Prior to filling the tank up, I tested the PH of the water and it shows angry red on the high scale of the API tester (maxes out at 8.8).
I was thinking I would have to buy a RO unit, but I tested the PH of the tank today and it is around 7.0 - 7.2. I decided to do some reading about GH and KH and after my testing I am unsure what is going on.
(All tests were done w/ API test kits)
The KH test turns yellow after 2 drops which reads 53.7 on the test kit information. That was easy to tell when the color changed; the GH test is not as easy. After 3 drops it turns from yellow to a yellow-green. It is not yellow, but it is sorta green
If I add more drops it gets darker, but the change was after 3 drops.
Tap water reads high PH and identical GH/KH readings. What would cause the PH to drop so much? Is it possible that the local water company has put something in the water that is dissipating over time? Am I reading the tests correctly as the water is "soft"?
Thanks in advance for any insight!
