Question from a Sump Newbie

[Azilla]

well its real easy.

From your overflow run a 1inch pipe. to the sump thats all.
Then from your your sump hook up your pump to a 3/4inch pipe
and run that to your tank. that is the return.

If u have a predrilled tank it will have a 1inch hole and 3/4inch hole on will need a 1inch bulkhead and 3/4inch bulkhead these are used to suppose the hole to pipe threw the glass. Its really up to u kinda look at your tank and draw the best route for both. then figure out what u need for a standard simple setup u dont need vavles and stuff.
