Hello.


Someone has tried something like this.
I want drain directly to IBC tank, below the water level.



Regards!

Hi Jesus,

What you are proposing will only work if you have a pump in the DWC. If you don't the back pressure will cause the DWC to overflow.

Creo que no puedo hacer sin un Bomba de agua en DWC.

I probably butchered that

Hi scotty435.

I think put one water pump or airlift water pump into fish tank, but I have the doubt if the drainage work.

I want to avoid using a sump tank.

Sorry Jesus, it won't work that way (not if the water levels in the drawing are correct). The water pressure in the DWC is lower than in the fish tank because the water level is lower. What will happen is the water will overflow your DWC instead of flowing to the Fish Tank.

Can you have the water flow from the fish tank by gravity to the filter and then from the filter by gravity to the DWC? If you can do this then you can pump from the DWC instead of the fish tank. You won't need an additional sump tank but you might have to protect the pump from plant roots.

Essentially you would have what we call a CHIFT PIST (Constant Height in Fish Tank, Pump in Sump Tank) system but the pump would be in the DWC not a separate sump. As you pump to the fish tank, the water would flow out of the fish tank using a Solids Lifting Overflow (SLO) or you could use a bottom drain.

Cheers

Why not lower the ft, then pump from there to the filter, with gravity to the dwc and back to ft?
