Air Pump science project?
i’m doing a science project and i need to grow some algae cultures in a somewhat large scale apparatus with several 3 feet tall, 3.75 in wide tubes. i need some small airpumps that are quiet and have both input and output sockets so that i can use specific gasses to aerate the apparatus. Any ideas on what i should use? they just have to move the air so that the algae remains agitated.
Some aquarium pumps have inlet ports, and they are usually designed to be quiet.
You could use a really cheap pump from Walmart. It would not have to have an inlet. You could place the pump inside a sealable plastic container. Drill three holes, one for the power cord, one for the pump outlet hose, and one for a hose coming from your gas source that will dangle free inside the container. Just seal the holes with some silicone and put the lid on.
