Watching Jeff Miotke’s youtube channel (. Jeff Miotke Aquascaping )
saw him using a drain and fill adapter from spare Oase parts. I was impressed enough to cobble one up myself.

It uses an Oase intake strainer which I had a spare of and an over the tank oase valve fitting which I also had a spare of. I bought a spare python gravel vac end section and fitted the hose end to the Oase over tank valve.
I have this screwed on to my Python tankside flow valve.
You can set the height of the intake and as such it stays put beautifully by itself. No livestock will get sucked up into the hose, and by adjusting height you can let it run unattended. Once water gets down to inlet air enters the hose and breaks the siphon…
Once you start filling the tank back up the inlet screen breaks up the flow force so substrate and plants are unaffected.
I have never seen Jeff discuss this in an of his videos I have watched, but I have been quite pleased with it. In my estimation far better than the Python hook…
