Wow! what a great idea! what fittings are those? mine leak really bad so I always have to turn off the water at the faucet but I'd love to be able to turn it off at the tank.
My question would be how do you clean the dirt and poo off the bottom of the tank?
Bump: Wow! what a great Idea! I hope you don't mind if I steal this from you! lol How will the quick disconnect fittings handle the pressure if you don't actually turn off the faucet? I'm also curious on how you clean the dirt and poo from the bottom with that method.
Thanks for the compliment. Except for the quick disconnect nozzle, the rig is made from slip fit PVC.
Everything not submerged is cemented. All the submerged pieces are just pressed tightly together so things like extensions for deeper tanks can be added on.
As for bottom debris, in my outdoor tanks with substrate, the wild Neos keep it pretty much mulm free. In tanks that are bare bottom, I just stir up the water to suspend the debris and the rig will suck up most of it.
I have to confess that w/ all my indoor project tanks, all are planted with some kind of carpeting plant (HC, Glosso or Monte Carlo). Any mulm is under the carpet so visibly there is no debris. Also I haven't done a water change on my indoor displays for quite some time. Really all I do is top off w/tap water.
Lastly, there are o rings on the quick disconnect nozzles so with faucet water pressure there should not be any leaking. I did find that if you orient the connection horizontally, the weight of the hose can cause leaking from the joint while filling. That's why with the revised version, I oriented the connection to the hose vertically. Hope this helps in building you own H2O changing rig. Good luck!
