My first ever planted tank, pH kH % Co2 questions
I have a 55 gallon tank with two aqua tech 30/60 hob filters. It's mediumly planted with some rocks, goldfish and ghost shrimp. Its been up and running almost 4 months. I just got some test kits, my pH is 7.5 and my kH is 4 so that means my Co2 is about 4.7ppm, right? Should I add Co2?
