Thank you so much for the quick response! You are always so helpful and I appreciate it very much.
I am doing exactly as you suggest; connecting the ozone generator to a controller which measures the ORP level in the tank and making sure that the ozonized water flows through plenty of carbon before returning to the main tank. I think I may start at the lower end of the ORP level, setting the controller around 275 or so until I am sure that all looks well.
Is there anything I should watch out for specifically in terms of possible ozone poisoning? Is there any sort of symptoms a seahorse might exhibit if it was suffering ozone exposure? Thanks again for your help!
