Splitting an air pump

[Chris 5]

Hi all, 

I am starting a fish rack with 4 10 gallon tanks. I will be running 4 sponge filters but I'd prefer to run one air pump. Was looking at the ap50 or 100 but am unsure if there is enough pressure to run 4. Anyone have experience with this? Thank you in advance.

I have split smaller pumps 4 ways before with out much effort. I got one of those 4 way gang valves. Then you can control the flow to each output. If you run them without a valves you will have a real hard time keeping flow to each tank. Maybe get the 4 way and setup a bleed valve before the gang so you can reduce the total flow while also tuning the flow to each tank.
