Air Driven Aquarium Pump House

thingiverse

It's a pump, that looks like a house! ... Okay, that wasn't all too funny I admit. But it really is a tiny pump made specifically for your aquarium! All you have to do is connect one air hose to it and then another tube to move water wherever you want. In the tank, to a filter, or directly onto something! It looks sort of cozy and I've arranged a few in different sizes to resemble a village. So far no shrimps have been sucked up into it but the one I'm using is also very small. I use mine to lift water up to a gravel filter inside a pet bottle and it works quite well after a month. The hose got a bit clogged up, but that's what you can expect from regular 4mm air hoses.
