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've just created a fish room... and have recently bought a large capacity air pump to supply air to the entire room...

I've yet to set it up so this is not from experience... but I have asked talked to a number of people (local and internet) who have such air supplies in their fish rooms...

I've been told that a loop around the room is essential... but do not put valves/taps into the loop... Instead make a PVC "U" coming down from the loop... across... then back up into the loop... put the taps/valves in this U... The extra U helps to maintain equal pressure throughout the system.
Originally I planned to loop the room... then come down from the loop with T's...

I was told that the loop around the room will ensure each T has equal pressure... but the pressure within the T will greatly vary...

Using the U's instead of T's will keep the pressure balanced in the U itself...

Again, this is what I've learned through research, not experience, so I cannot vouch for the information personally, although it made sense when it was explained to me...
