I have a 20gal DYI sump. Where the water drains, also where the skimmer will be, the water level is about 12 inches. I used to use a remora pro in the sump which worked out ok. Now i just got a euroreef cs6-1. They recommend 6-8" level. But in order for me to do that i would have to do some work on the sump. Is there any problem with running the skimmer at this level?..THanks.
