I'm looking to get a good return pump for a 90 gallon (reef ready) AGA. The predrilled return hole in the overflow box will only allow me to put a 3/4" bulkhead on it, so I'm really looking for a pump that has a 3/4" output.
What do you think about the Blueline 1100 pump?
Or do you have any other suggestions?

FYI, as long as you can accomodate the diameter of the pump's input, it doesn't matter how small the output diameter is. You can't restrict the water pulled in by the pump, but you can restrict the water leaving the pump as much as you need. So, for example, if your pump has a 1" in and a 1" out, your sump MUST have at least a 1" diameter for water to enter the pump. But you could reduce the diameter of the water leaving the pump to 1/2" if you wanted.
Think of it in this way: if you have a powerhead in your tank and you think it is too powerful, you can adjust the knoby-thingy to reduce the flow rate. The return pump is the same thing except on a larger scale.
I hope that made sense. Anyway, buy the best pump you can and don't worry if it's too large (within reason of course
). You can always reduce the flow.
