Thanks again Chompers.
Anouther question. I am running into some clearance issues, resticting the tripple overflow design. Useing 1 1/2"ers
So both the eheim I have now, and the mag 9.5 I will get later use 3/4 outlet.
Keep in mind I am doing only 100 gallon tank.
I also noticed that you have your overflow valves closed a lot on the silent setup.
If I can make 1" pipes fit for the 3 overflows,,,,, and use 3/4 for all the rugf, do you think it will still work??
The 2 main overflows would be 1.57 and 3/4 would be .44 thats little over 3.5 times the area, plus the little bit going down the third pipe would be close to 3.75 times the area of the incoming fresh water. I think?
I did a mock up, and with 1 1/2 pipes, I can't get my receiver in the cabinet far enough to close the door, and wife happened to be supervising, and said ""your not leaving it like that are you"? translated into man talk, do that with a brand new 700$ cabinet and your cut off!
