I had decided on the euro-reef skimmer. They have one advertised for 200+ gallons. When I talked to them they said that for a 230 gallon tank I would need a CS12 with is too tall for my cabinet. I have only 30max under there. I hate when they advertise that something is capable of doing something and then when you go to order...its not true. I really like the reef creations one, but to clean it you have to disemble 8 screws to take it apart. I wouldn't want to do that to empty it each time. can you tell me about others that are really good too? thanks guys
