Yea it works excellent. I was going to drop $1k on the Geo kit. What a fool I would been! I've spoken to a guy with a similar setup and I have a reef octopus skimmer. I will have issues with the tube that feeds the recirc pump as its the only part not ozone rated. I plan to buy 20' of tube and replace it every few months as there is no 5/16ID ozone rated tube. Try it out. You don't have much to lose. 50 watt unit for roughly 100g displaced total. I have it to about 20% which is the lowest it can go. I cycle it twice a day for 2 hours. You can't smell anything and the water is crystal clear. The best part about it is that it has zero impact on my skimmer operation. If anything, it's stripping out more now, but the flow is stable as could be.
