To any one who has one of these linear piston air pumps,
I am currently running 12 tanks in a small fishroom with a mismatched assortment of power filters and sponge filters operated by a small handful of diaphragm air pumps. They are noisy, all of the different power filter configurations and cartridges are getting tedious, and the prospect of any regular reconfigurations is a nightmare.
I would like to switch to a linear piston pump with a manifold, and envision myself running about 20 outlets for now (sponge filters in all tanks, box filters for peat/carbon when necessary, brine shrimp, etc.). I have an opportunity to purchase a used pump and manifolds for a reasonable price. The potential problem is that the pump that is available is over-sized for my needs (rated for 40+ outlets). I know Jehmco offers a pump that would fit my needs (20 - 25 outlets), but by the time I bought the smaller pump from them, along with manifolds and other accessories, it would be far more expensive than the available used set-up.
So, my question is this. Would it be a problem to run only 15 - 20 outlets with a linear piston pump rated for 40? I've read Ted's account of his fishroom set-up in which he states that back-pressure is not an issue with linear piston pumps (within reason), but that he also installed a bleed valve in case he needs to let off excess pressure. If it makes a difference, the manifold(s) I would get with the pump would allow me to open extra valves that didn't feed into a tank.
Any thoughts or input would be greatly appreciated, as I would like to move on this quickly, if I'm going to move at all.
Thanks
