I run a VarioS4 , a VarioS2 for my REGAL protein skimmer and they are awesome pumps, THERE is no doubt about it and for the price ya can't beat it... There was a person on here that did an experiment with a VarioS8 vs an EcoTech Vectra M1 and for a 9 month period he ran both the VarioS at 75% and the EcoTech Vectra @ 75% and just after the 9th month period, the the Reef Ocoto VarioS had lost some of its gph vs the Vectra pump that did not lose any of its power. It was measured through #Neptunes FMK Monitoring kit and it clearly it showed that the VarioS return pump had lost some of its gph which was very interesting over the 9 months.. I have always ran 1 EoTech M1 for a return pump which these pumps are supper awesome pumps but you must maintain them and soak them in Citric Acid to remove any sort of calcium build ups every 3 or 4 months or the motor will start to swell on ya like it did me and I had to return mine in since I never took the time to clean it and after about the 10 month is ceased up on me due to the calcium deposits. Now, I clean all of my pumps every 4th month and let them soak overnight in my BRS Citric Acid. If you maintain them they will last for a long time, thats a (FACT).. Instead of going with the new Reef Octo Pulse pumps I instead went with 2 EcoTec MP40QWD on each side of my SCA Rimless 150 build and 2 NanoStreams TUNZE 6055's that will be mounted on the back of my 150, so there will be no dead spots in the tank since I will be going with a minimal scape.
