Curious to hear the GPH
I made mine with 3/4 pipe and by my calculations it is running between 350 and 450 and hour. MY pump is an old pond pump I have had for 3 years, still works great so I used it with 1/2 return line and the flow is equaled out I think it was rated at 500 when I bout it(all the stickers are gone so I'm not sure what it is anymore). The cool thing about the design is the part with the 1 inch pipe can be raised or lowered to adjust the flow up or down.
I also used 2 overflowes to feed mine though, this guys design is pretty solid, mine has been up and running for 5 days with no issues, and last night we had storms and the power went out while I was sleeping. NO
WATER in my floor and the thing was running just fine when I got up, wish my alarm clock would have automatically reset...lol
here is my pics of the design
Ignore the small 1/2 inch down pipe in these pics that was just to cut it back to test with a powerhead until I found my pump. Once I put the pump in I went back to 3/4.
