The sicce psk1000 has been known to go out. Personally I would go with the sro1000 model for your tank. There is such think as "over skimming" and can occur when pulling to much nutrients out of the water. From what I heard when calculating the amount of water for a skimmer you don't include the sump (I could be wrong). But the 1000 should be enough. They are made out of great material, and reef octopus offers warranty on both the skimmer Body and pump. Even the most expensive pump on the market, the red dragon's have been known to go out and they only have a 2 year warranty. Reef octopus offers 3 year warranty on the bubble blaster. So you should be set for a little while
