I run it constantly on 80l tank without reducing humidity of air intake. The ozone production in this situation may be reduced in half or more. I can't measure the amount of ozone, but it makes good for the aquarium. Fish grows healthy and the water quality is improved despite the extensive feeding of the youngsters up to 4 times a day. No symptoms of ozone overdose. Shrimps in this tank are also happy.
