I am finally building a 90 gallon reef. I going to use a sump for my filter. What size Mag drive return pump should I use?
 
What size sump are you using, and do you know what your overflow is rated for? Need to match the pump and the overflow.

If it is a standard reefready tank (( rated for about 600 gph )) I would suggest either a Mag 5 or Mag 7.
 
I would go with a 900 gph pump, then dial it back as necessary with a valve or T off of it to feed additional areas ie. refugium, reactors, etc.
