Need help with overflow plan

hani · 04/10/2018, 03:24 PM

Hi, am new to using sump, I bought a cadlights versa 90g, it came with corner overflow , the tank has 2 holes one for the drain and one for return, I guess this drain style called durso, although am going to use it for planted tank, I thought I will ask here as you guys have the most experience, should in turn the return to emergency line? Or I Can use optical sensor (Ghl) to shut the pump off when the level get high. Am trying to avoide flooding.
Thanks

I'm not sure what you are asking. Your sump should be able to hold the amount of water that would drain out of the main tank via the corner overflow, and conversely, a properly designed sump will not allow you to pump more water into the tank than it can handle (baffles limit the amount the return pump can pump into the tank before it runs dry (less than what it takes to overflow the main tank), and a valve on the return line will allow you to make the drain flow equal to the return flow, to keep the pump from running dry).

I would use it as an ermergency and do an over 5he back return.

The two hole drain set-up is often referred to as a "Herbie" drain - you get the quiet siphon doing the heavy lifting and a second "open" drain in the event the siphon gets fouled.

It's a far better bet than a single drain, so I'd go that way. Search out the herbie. pour some coffee. it's a long, long thread.

I have the same tank style you do.

I ignored that it was a drain/return and made it a drain/emergency (Herbie). To return water to the tank, I plumbed PVC up and over the side of the glass to drop water back in. That way I have two drains for safety to avoid flooding.

Its a little ugly and some people don't like the sight of the piping over the side, but I much prefer that to a wet floor.

What about using an optical sensor or even a float switch inside the corner overflow to shut the pump off in case the durso clogs.
Thanks

I say use it how it was designed to and keep the clean look. Just make sure to setup your sump so it can withstand the drainage and water in the plumbing and you won’t have an issue.
Your tank is meant to look sleek and clean, I’d personally keep it that way.

I wouldn't worry much about a Durso clogging. The problem with them is the noise. If there is more than a trickle going down them, they gurgle.

I wouldn't rely on sensors or switches for this. I would either just use the Durso, knowing its limitations, or do a Herbie as others described.
