At the request of a member here, I'm posting how I set up my air supply for my fish/shrimp room.

I run a 55LPM Kamir air pump. From that I used the rubber elbow hose supplied with the pump to attach to a 19mm barb irrigation piece, then into 20mm PVC pipe. I placed a T piece above this to create a loop using the 20mm PVC pipe, with a PVC elbow in each corner of the room.

Running the pipe in a loop ensures pressure is equal in all areas of the pipe.

note that the pump is on a shelf up high, higher than the water level in the majority of my tanks. This prevents back siphoning when the power goes out, and I've seen a few air pumps filled with water when this precaution hasn't been taken. Don't trust oneway valves either, seen too many fail to ever trust one.

From the 20mm pipe, I used 4mm threaded irrigation taps so I could connect standard airlines. Note I used threaded, not barbed, taps. The reason is that the threaded taps can be installed easily with no leaks, simply use a 3 to 3.5mm drill bit (test it on a scrap piece of PVC pipe first) to drill holes into the PVC pipe, then simply screw the taps in. The PVC is soft enough for the taps to screw in and forms a tight seal.

I grouped my outlets because I have racks and need to have the outlets at either end of the racks for easy access.

I used hooks and cable ties to hold the pipe close to the roof because I wanted it to be easy to dismantle.

Nice write up mate! Nicely done!

Very cool setup, simple & easy, awesome work dude :victorious:

Thanks for sharing. I wish I had a shrimp room that I could use an air supply system :-(

Just like a pro mate, good job.

One pointer I might add is, taping the thread in the pipe! cut the head of a self taping 3.5mm metal screw, and it cuts the hole and puts a thread in at the same time.

How dose 25mm work? as I over kill and use 40mm.

To many times I have seen people use 13mm pipe not used in a loop, it doesn't take long to kill the pump from back pressure and it is uneven all round, my but in mate sorry.

cheers mate! :) looks great! that pump looks like it can move some air :encouragement:

Never had a problem with the 20mm pipe, I would use 40mm if I was using a bigger/more powerful pump.

Thats a good tip about taping using a screw. I just use pliers to push/twist in the tap. Used to use my fingers but it gets painful after the first tap.
