Media piston pump question

[Maximus297759]

I’d like to add it to aquarium with only 7 air outputs will this hurt the pump being restricted. I’ve read it will idle down if pressure high.  A good diaphragm pump will be at least 90watts so in few years this medo pay for it self. If idles down control pressure I bet want use much or 45 at most.

I would say yes it would be to high pressure. Depending on how deep your going. You could always set up a relief valve. It’s just a spitter in your PVC main line that would have a valve to relieve some of the pressure. Adding a 10’ tube with small holes after the valve with help with the hissing noise it will make. You then adjust each drop and the valve to give even flow at you preferred setting. Takes a little work.

piston pumps do save money, lower noise, better even flow, not as many cords. And if you don’t already own one aquarium coop has one on their site. I have one and very happy with it. Click the link.
