Hello everyone I am a NEWBIE. Quick ? about KH and PH. I am getting ready to do a 75 gallon planted tank and I will be using an automatic setup. I just tested our city water and talked to the "guys" who take care of the treatment of our water. Our water is currently at 7.4 and soft maybe 1 degree KH. If I use Baking Soda to bring up the KH will I have to worry about my PH rising and affecting the fish? Or depend on the CO2 to take care of my PH. Oh and I bought Greg Watson's write up great stuff.
