overflows

[scuglass]

muck that is what i am planning to do just a few questions

do u have elbows pointing down inside the tank so no air is taken in ? or is air able to get in there and then out of the external standpipe?

does ur overflow box go down to the bottom of the tank? would there be a problem with it not going to the bottom and just hannging on the inside of the tank(silicon maybee)

is it quiet

thanks scott
