 surface skimming...
My local fish shop wont do the teeth shape for my surface skimming overflow so i need to either make my overflow from acrylic and glue that to my tank or...
What would you think of making 2 separate wholes to the back glass of my tank, one at the right place so half my bulkhead would be off the water and the other one right in the midle so i could both do surface skimming to my tank and catch free floating particles in the water with the one in the middle so have both mechanical (sump sock) and surface skimming systems for my water intake, i would control the flow making 2 separate plumbings to my sump and putting a valve in the midle bulkhead.
My english is not perfect so i apologize for it, i dont know if i make myself clear in my idea if you dont understand please help me and i will try to explain better. |
