OK, i just got my new 100mg/hr red sea ozonizer. I have a few questions about its use. It says to hook it up to an airpump to force the flow of ozone into the tank. I did this, but I was wondering if I need to control the airflow from the pump with some sort of valve? Also after hooking it up and running it for 2hrs at about 15-20%, the whole floor of the house smells like ozone. This can't be good, and the smell is getting to me. What am I doing wrong? Many of you posted that if used in small amounts, you don't smell it. Well I certainly do. I have it connected to my skimmer through the ozone/Ca Reactor JG fitting. My skimmer is a aquaC EV180. Any thoughts? BTW, i put some carbon in a bag directly under the outflow of my skimmer. I'm not sure how to hook it up, so that I have carbon in line with the skimmer, as I don't want to restrict the outflow of my skimmer.
