What's the best pump for a 155 bowfront?

[Razor]

The pump for my sump and my closed loop are two seperate Iwaki 40s and my closed loop pump just died. My thought was to take the older Iwaki 40 from my sump and place it on the closed loop and buy a new pump for the sump. The closed loop has a Oceans Motions Squirt on it which has a GPM limit and the Iwaki was working well on it. The Iwaki was working ok on the tank, but because I had it with my old tank I used it instead of really finding out the best turnover rate for the tank, what should the turnover be?

My requirements for the new pump are:
1. The pump needs to be able to provide the correct turnover rate for the tank (155 Bowfront), which has 4 return nozzles.
2. Must be quiet or I risk my wife killing me (or the fish).
3. I would like it to be energy efficient.
4. Reliable, the Iwaki have been running for 5 years straight.

Any suggestions?

I forgot to mention above, the pump needs to be an external.

If you like the Iwakis, PanWorlds are the same pumps just cheaper. These are very reliable pumps.

FWIW, IMO the return pump should not be used to determine tank turnover. You should be just deciding how much flow you want through the sump and sizing the pump that way. I perfer a slower turnover though the sump giving my skimmer more time to filter, and getting my high tank turnover otherways. You have a closed loop that counts towards the turnover. In my 58 my return is only pushing around 300gph after head loss etc..to me thats a good match. I turnover the tank with a vortech and tunze nano stream.

What happened to this forum? I know I haven't posted in a while but this used to be a great forum filled with opinionated bastards who loved to tell everyone what to do, and that's why we loved it :lol:

Come on guys, I really need opinions on pumps.

Everyone on this forum has a tank, which means you all have pumps. Please reply with the type of pump you have and your opinion on it.

I'm using a PanWorld for the return on a 180 - good pump.

I'd like to know how everyone is running their tanks with no pump?
