Beginner in need of some advice

[Sunee]

I have a 60 gallon and have a Herbie style drain system, 1" primary drain with a gate valve, the second 1" is the emergency drain. There is a 3/4" return returning about 250 to 300 gph (you could go higher with the 1" drain) - return pump is the Tunze silence 1073.20. The system is dead silent an I've had it running for about 10 months with no problem. It is an option for you.
