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.

Don't worry about low KH, it really won't matter. You're going to be heading for a soft water, low pH tank anyhow. Some how I doubt that amazonian and malaysian rainforests manage over 1KH in most places, and many of our tanks are similar. They all do just fine; it's KH stability that counts.

Baking soda will add sodium. Ever heard of the term salting the earth, or wonder why the egyptian economy went flat from drought thousands of years ago? You can thank sodium. It'll raise your pH too.

So, when you say KH stability- are you saying do regular water changes and I'll be fine or is there a product I need to add to my water supply to stabilize the KH.

Thanks

Just keep changing with tap. You've got some good water for growing plants as far as general parameters go.

Thanks man. I'm moving up into the Tank World and I want to make sure my homework is complete because I'm sure I will have some bumps and I want to know how to get over them :).
