I have kept fish for 40+ years and have tried to keep live plants on and off over the years. Just now I have decided to try co2
injection on a thirty gallon tank. So far it seems to be working. I currently have a 150 gallon community tank A 50 gallon with thirty angles. A 50 gallon with the koi from the pond. A 30 gallon planted that has guppies and cory cats. I have a 90 gallon that was my saltwater reef and is now empty.
