I believe 700gph was the flow through the display tank and sump as he states he also has 2 koralia 2 powerheads and 1 koralia 1 running which would yield 2300gph or 25x turnover per hour.

With ozone remember that it will also convert your ammonia and nitrite to nitrate very fast so you will notice that you levels will climb too alot of people will run ozone with their becket skimmers and bent the air outside then u don't have to worrying abbout it. That is what I did

experts wanted :) re: ozone

I have some cheap ozone machine I found on ebay... it's piped into my skimmer air intake... I'm a lazy bastard so I just randomly run the ozone a few hours a day.
or overnight sometimes.
haven't noticed had any problems... but haven't noticed any major improvement either. aside from clearing up the smell after I feed silversides.
