I have 180 gal tank with the aqueon model 4 sump (30gal) . someone told me to get the laguna 2000. But for only a little more I could get the Laguna 2400 and I wasn't sure if that would be to strong .
I'd say go for it. it isn't hard to disperse the flow if the output is too high. splitting the output into multiple nozzles, a spraybar, a larger tubing output...
What are you using to drain water into the sump? Ie overflow box, bulkhead size, etc. You dont want a pump that will be stronger than your drain. Find out what your drain is rated for and go from there.
