mag pump question

i set up a 60 cube with a 9,5 return. return line cant handle it so i put a ball valve on it.should i just get smaller pump..is it bad on the pumps to restrict flow
 
You can restrict the pump. If you have the cash consider getting a quite one 2200 pump. They have the bulkheads and everything right on them and are easier to service than the mag pumps.

What kind of overflow do you have? Can you describe the plumbing and diameters of the pipe?

Running the reef central head loss calculator you are pushing around 680 GPH with the 9.5 if you are using 3/4" pipe. That is pushing the edge of a typical 750gph overflow (which is likely pretty noisy).
 
I've been using that same pump for years with a ball valve on it running at about 3/4 flow. It just keeps chugging along. Jeff, from Lifereef, suggested that arrangement and I wasn't about to question his knowledge. I bought an extra identical pump, which I use to pump water up from the basement. I'm too old to carry buckets of water up the stairs anymore.
 
Since I have a 60 cube and I have a new 9.5 that I am about to install, Can I ask how big your drain line is?
 
Drain should be 1.5", you can go to 1 1/4", larger is quieter. For the return lines from the pump I would do 1" on that size tank, way more flow than 3/4" which allows a smaller pump (less $ and less electric).

The flow from the return is based on resistance from the pipe, larger pipe helps a lot, even when reduced at the tank
 
Would having the drain and return being 1" hole and pipe being 1.5" would be a problem? Having a beananimal overflow 3 drains and 2 returns.

Well, i just measured to confirm, but I have a 1" supply and a 2" drain, so I don't have any fear about the 9.5 any more. Plus it will be providing manifold flow to power a carbon and a bio pellet reactor.

That will use some of the extra gph the pump is pushing out. The initial surge will send carbon flying in the reactor, put a sponge on top and below to help contain the carbon
