Hi, I think neglected to realize that the siphon part of the herbie setup is predicated on the bottom of the drain being underwater at the sump. Is this correct? In my quest to have the most girlfriend-friendly least amount of noise tank, I think I overlooked a very basic requirement...I'm a dummy, and just realized this. Questions:
A. What will happen if I just dump the drains into the filter and then sump as shown? Just noise?
B. Can I build a small box 3" or so in height out of acrylic to hold water above the filter element that I can run the drains into? This will put the drains underwater, and I can retain the sump system I have, but am unsure on sizing the holes/balancing flow etc. to drain the water onto the filter media. I think this may be hard to make work.
125 gallon tank, only filled halfway because it's for a turtle. 3/4 (main) and 1 inch (tall standpipe) bulkheads in both corners, returns over the back of the tank.
Thank you!
