Hello, I'm new to saltwater tanks and planning the setup for my first one, a 20-gallon. I'm a bit confused about pH and KH.
What is the KH level I should be striving for? It seems there are different answers online. Or does it depend on the fish? How can I increase or decrease KH?
My understanding is that KH and pH will be significantly affected by the sand, right? In that case, how can you properly test and adjust the water before it's added to the tank and interacts with the sand?
I've also heard that my pH levels might be too low because of a lot of CO2 in my air (small space, few windows, lots of people). Is there a relatively inexpensive way to reduce CO2 levels? I don't have a protein skimmer. Is there media for other filters that can achieve this?
Thank you!
