My tank is a 65 gallon reef with all soft corals. I'm going to buy a new in sump skimmer and there are two sizes available for the model I'm getting - one that is recommended for tanks up to 110 gallons and another up to 210. Because the larger skimmer pumps about twice as much per hour (600 vs 317gph) and is 4 inches taller, do you think its worth it to spend a little extra?? I'm wondering if the larger skimmer would be more benificial to my tank or if it's all the same after a certain point.
