I'm trying to understand your question but I'm a little confused. The water leaves the skimmer when the skimmer fills to a certain level, then gravity takes over and forces the water up the 3/4 inch pvc pipe and out into your sump or fuge..etc.
On your remarks toward everyone here who's trying to give you advice.... You say only one person is helping you.... on looking back at your thread, nobody posted more than once...??? And everybody who posted was trying to tell you that the skimmer design you posted isn't exactly the best, and also not the worst.
A few questions you need to ask yourself before proceeding...
1. How are you going to be able to change the wooden airstone when it gets clogged? The pipes are all glued together right? and the main skimmer body is over 40 inches tall.... my arms aren't that long, are yours?
2. Do you have room for a 50 inch tall skimmer? That's over 4 feet tall.
3. Did you consider that the skimmer design link posted by 'brc' could be built using cheaper materials? How about some 6" pvc? Im sure you could modify the pvc fittings to accomplish the same design for much cheaper than the acrylic.
4. The skimmer that brc posted will be much more efficient, longer lived and for the most part maintence free. The one that you posted looks like an absolute nightmare to me. They both will take about the same knowledge and resources to build. Why not go with the best of the two?
