Air Pump & PVC loop for fishroom. please advise

I purchased an airpump for my fishroom

Hi Blow 80 Pond Air Pump Ref: HP80
Exhaust Air Flow Rate: 80 Lt/min
Voltage: AC100/120/220~240
Power consumption - 71w
Frequency - 50/60 Hz

I am planning to build a loop from pvc pipe around the ceiling of the fishroom
and then connect the airline for up to 30 tanks to the loop using these manifolds

However, from reading around

"...When installing the air plumbing, think about loops. Air pressure is maintained evenly in a system that does not have any dead ends. My room has a large bisected loop. The loop goes completely around the room and a pipe runs across the center of the room connecting opposite sides of the loop. I used 3/4″ pvc for the plumbing. This is another area of savings over a regenerative blower, which uses 2.5″ pvc adn fittings. The cost difference between plumbing the air with 3/4″ vs/ 2.5″ PVC is significant."

So does this mean that with my pump i will have to use 2.5 inch PVC, or can i build a loop out of 3/4" with my pump, which isnt a linear piston pump, but instead a linear diaphram pump.

Has anyone any experience with this.. i'd love to use a loop of smaller diameter, but i have the pump already so i will work around this..

Hope you can help

I was told that a blower uses single run whereas a linear pump needs a loop. I don't know if it is in fact true, or why it would make a differece. Some people use 1/2"pipe, but bigger is better. I don't see why you couldn't use central vac pipe which is much cheaper, other than the thin wall might be difficult to screw into without leaks.
