I have about 95 tanks and 100 or so valves running, there is more than enough air. I use Hydro sponges in all my larger tanks and all of them have air stones in them, most tanks are small, less than 123 inches in height. ( NOT REally more like 12 inches !!!!)
but I have 3 55 gallon tanks, and two 30 gallon tanks, all have two large hydro sponges with air stones. things work well.,
My 80 watt has been running for 4 years 24 hours a day, more air than I need, and so quiet all you hear are air bubbles...............
I believe you can not find a better pump for any fish room..................

With a blower I used 1.25" piping to feed the tanks & pushed a valve into this pipe above each tank. The blower produces volume but little pressure. Would a linear power a similar system or should it be tapered off to smaller diameter piping the further from the pump?
