Viper, I run ozone and it works well, it helps with water clarity and fish disease.
I run the 100mg aqua medic unit through it's own skimmer, I am currently running it at about 70% in a 1650 litre reef system.
You need to suck the aid through a dryer first, then through the ozonator and into a skimmer, I prefer just a small aqua medic skimmer independently for this.
You will also need a mv controller and probe to monitor your ganja MV's which you don't want more than 500, this will tell you weather you can run the ozonator at 100% or lower.
Go check my thread under ShaneO reef tank and you will see my pics.
Hope this helps in simple mans English and not going over the top.
