I have a tank that has been cycling for about a week and the pH level is arount 7.8-8.2. 8O There is nothing living in the tank right now. During 1/2 of the week, the pH was about 7.4-7.8 and it jumped today to about 7.8-8.2. What could be causing the pH level to rise? What can I did to lower the pH to 7.0?
