How to control pH

Hi, I am thinking of buying a pH controller to control the pH. But I do not understand how to use it. Any one can help to explain? Thanks.

Usually pH is to control the your solenoid valve for CO2 in your Calcium Reactor. 1st why do you need to control pH? What is that use for? You must ask yourself.

Hi, thanks for answering. I found that my pH is too low (~7.7). I have tried adding pH buffer but it still stay at ~7.7.

usually pH is not the main problem.

PH low may be due to many things.

1. The test kit you use. it will be easier if you have a pH monitor.

2. Type of salt you use.

pH controller is not meant for increasing pH in your tank.
