can you run two pumps at once? Say have one pulling water from the sump and then pushing it through two nu clear canisters and then another pump pulling water from the canister and back into the tank? would this increase turnover rates if I cant find a pump big enough to get the turnover i want...?
 
generally you are asking for trouble when running two pumps. But if you are talking about having an external 2nd pump that is plumbed in-line with the canisters, then it might work. I think you would be better served to just get a larger pump.
 
Actually I like the idea of two pumps. You might consider using one pump on each canister. Basically two identical parralel systems. There are two advantages, one, you have redundancy in case of a pump failure and two, by separating the canisters you effectively cut in half the backpressure created by the filter itself thereby increasing the efficiency of the pumps.

edit: this assumes unpowered canisters, not familiar with nu clear products.
 
Pumps are typically never run in series in a closed loop. You can run them in parallel, but you would have to have check valves on the discharge sides, otherwise if one failed, your flow would just be a loop around the non-running pump.

Yes they are unpowered filters. Hmmm I really wanted to have a 25 micron filter pad then go to a canister with bio media then return back into the tank. But I'm thinking about the parallel set up now...

What the problem with running them in series? Just wondering why it would not work.
 
I would just use a big pump to push the water from the sump through both canisters to the tank. Although, you really don't need the canister full of bio media if you have a sump.
 
You can run pumps in series, works very well. You need to match the pumps though by using the same spec pumps and preferably the same manufacturer.

I liquid cool a computer using two pumps closed loop in series.
