Sump size for 90 gal tank

Would a wet/dry sump setup rated for a 120 gal be large enough for a 90 gal tank? Or should I go with the bigger one (rated for 240 gal I think)? I am going to add an algae refugium to this system... The difference in $ is 120 bucks.....

Sorry Old Salt - I am unfamiliar with this brand Del Ray.
If the manufacturer states that this unit is rated for 120 gallon - that doesn't really tell us much but marketing stuff.
See if you can get specs on the unit - specifically the overflow water flow rating iin gph, and the return pump furnished ( if one is furnished ).
This info will help you decide actual and potential flowrate of the loop.

Don't know about Del Rey, but you should make sure that your sump has enough capacity for your tank.... i.e. "Room for error." Make sure that, with a 90 gallon tank, the sump has at least.... 8 gallons of play. This means that there are at least 8 or so gallons between the sum being at the minimum level for operation and overflowing. This is very important, because it will allow you to avoid topping off very fequently. You can go on that 1-2 week vacation without wondering whether you're tank is flooding.
 
As a point of reference, I'm using a 40 gal aquariumk as a sump in my 100 gal. As that's a DSB with skimmer system, I just sit the 40 gal tank below my 100 gal and place my EuroReef skimmer in it. I am, however, in the process of converting that system over to a refugium. Aside from the Nitrate-factory aspects of tricke filters, I woulkd also look out for their often limited capacity. As the previous poster said, beware of the tank suitability claims on the box. As Marketing professional, I never believe the crap they claim.
Hope this helps?
