• Diameter of Durso :(

  • Chad9037

What should be the diameter of the Durso pipe for a 600-liter aquarium? The return pump is a Hydor Seltz L 40 with a flow rate of 2800 liters per hour. It is said that 1" is too small. The author of this drain writes: Considering that one gallon is 4.55 liters, with a pipe diameter of 1", the flow rate will be 2730 liters per hour. Taking into account that the pump will not provide its full power at a height of 1.6 meters, we get equal values for inflow and outflow. ............................. I would like to hear the opinions of practitioners - what diameter do you have?

Can we calculate at 3.78?

That's why I'm asking for the opinion of PRACTITIONERS.

This pump won't be able to handle it. After the water is lifted up and passes through the pipes, let's hope it reaches 1000 liters per hour at the outlet. But you need to pump 3-5 volumes per hour. Over time, the pipes will get clogged inside... A pump with a minimum capacity of 5-6 cubic meters per hour is needed for a 600-liter aquarium. I have a pump set to 4.5 cubic meters per hour (Deltec HLP 5250) for my 300-liter display, and the output is far from impressive.

The task is not entirely correct, as it initially starts from the desired circulation of the "tank-sump" that should be achieved in the end. Then we calculate: a) the perimeter of the drainage part of the overflow box in cm. b) the diameter of the Durso. c) then we select the pump(s), taking into account the drop in performance due to the lift/bends in the pipeline/plans for discharge into the bypass/supply to substrate reducers...

It turns out they are right. A 1.5" pipe is needed.

How much are we planning to pump per hour? Why is it necessary to have 1.5"? Here's what they write here: If one with a 1" inlet is not enough, then just install two and adjust the valves below.

Well, considering that it seems you need 5-6 volumes per hour, then 600 x 6 = 3600 liters or 952 gallons. They write the same thing. 600 gallons - 1" 1500 gallons - 1.5" I get somewhere in the middle - 1.3".

It is better to choose a diameter with a margin and install a ball valve than to find it insufficient later and have to re-glue the entire drain.

I am planning to.
