![]() 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.

Or this^^^. The 3rd overflow is merely a fail-safe. You get the same silent operation from the one Sunee describes.

![]() i use stockman drains-never had a problem in 7 years and they fit in tight places.i also have no noise with them.i agree most chinese fixtures are a piece of dung-but i was impressed with the two i bought which are a basic strip with 9 3 watt crees with lenses in a housing for the 2' and the 4 foot has 18 leds.for the price i paid i couldn't complain.and as i said the par is the same as the illumenex at 3 times the price

![]() So I've got 1 return pipe with a 90 directed down into the over-flow (Like Beananimals) and the second 90 is pointing upwards (again like bean-animal).
So I've got my over-flow drainage and my over-flow protection, both will drain down into the sump. For the return then... with 3 elbows and 4 foot of head back into the tank, I would require a 600+ gps return pump... is that correct? |

I think it is very much worth it and anybody that has one will probably say the same thing. The added security against a flood is worth it by itself. The fact it makes little noise compared to other overflows is an awsome added bonus. BTW, you don't need a box that extends the entire length of the tank like in the diagram. The added space the box will take up will be small.
