Re: [Killietalk] PVC air manifold vs. lots of airline tubing

[Brian Watters <bwatters at shaw_ca>]

In my previous fish-room I used an LPH 100, which is the next to largest
linear piston pump sold by Jehmco. That pump provided air for more than 120
tanks as well as to large airstones at the bottom of each of four 55 gallon
water storage tubs. The latter were at least 4 feet deep and if I opened up
the valves to each airstone completely I had so much air that the water
would appear to "boil". Even with all that I had so much spare capacity that
when the main manifold cracked three-quarters of the way around the piping
and the air was blowing out at an incredible rate, the pump simply adjusted
the output and maintained pressure to all the tanks and the tubs without
noticeable difference.
