overflow standpipe help
i recently got a 90g RR tank with corner overflow. i am at a loss as to how to do thestandpipe. im leaning towards a durso but from what ive read they tend to be noisier and more finicky. i would love to do the system that has 3 drain pipes one under full syphon one as just a makeup drain that can go to full syphon and the backup but i only have 2 holes obviously one for drain and one for return. any tips or tricks you guys may have to offer would help alot.
