How to lower ph?
Hello all. The ph in my new 46 gallon tank is 7.6 After looking at the ph/kh/co2 chart, it looks like I will need to lower my ph if I want Co2 to stay suspended in the water. I have a large piece of malaysian driftwood on the way. How much can I expect this to lower my ph?
The other thing is I am wondering if my test kit is reading wrong. My wife works in the same city as we live and she uses a ph meter on their water daily. This ph meter is calibrated 3 days a week. She said it has been reading at 8.0 or higher.
So if the driftwood doesn't lower it to a more reasonable level, is it baking soda I add to reduce ph?? Thanks!!!
