Overflow Boxes

[PotatoPig]

I’m setting up a new reef tank - my last I used a siphon overflow, for a few reasons this time around I want to go with a drilled overflow.

The tank is 75 gallons, but I plan to run the system on a relatively low turnover through the sump - somewhere around 200gph.

First time using one of these so have some questions:

I’d like to go with a Durso overflow - can this be used with just an emergency drain? Most diagrams I see show it with a permanent siphon with the durso as a secondary drain.

Can most overflow products be converted to a Durso?

Does anyone have any recommendations for products?

Thank you.

Bumping for the sump hobbyists.

A Durso standpipe is just that; a standpipe set up for tanks with only one drain bulkhead, to attempt to quiet them…

This is to say, durso standpipe(s) can be put on a tank with any number of drains… the question would be, why?

This is not what I would consider to be a easy, maintenance free way of keeping drain(s) silent, and drain methods have come a long way since these were popular…


I’d recommend looking up Herbie (dual) and BeanAnimal (triple) drain configurations as a starting place!

Durso, Herbie and all the other variations on the theme were intended for one main purpose....to run SUPER HIGH FLOWS through the limited drain and return holes in a common Reef Ready aquarium.

The reason anyone ever wanted to do that in the first place is because powerheads like we have now (that use propellors; thanks Tunze!!!) didn't exist yet. So people used their return pumps....but flow that way was obviously VERY limited by the drain capacity....and the drains were VERY noisy when run like this.

YOU are not doing anything like that with your system.

As you stated you are aiming for around 200 GPH, which a 1" gravity drain will handle without issue, and it will do so silently.

Not even a Durso should be required, let alone the upgrades from that.

How are you planing to set up the overflow, or will you be buying a predrilled tank that's already set up with drains?
An open standpipe is a bit sketchy, FYI, so let us know....something like this around it is MUCH more ideal:
