Nice anecdotal storyOddball;618874; said:Years ago (I don't want to say how many), We used to aerate tanks, during power outages, with truck inner tubes like the ones you go tubing down the river in. They can be filled with a bicycle pump so, you can use them over and over again in a blackout.
We'd fill the tubes then connect them to a home-made manifold (stainless steel pipe. Today...PVC can be used). A basketball inflation needle valve would be mounted to the tube's valve stem. A short collar of rubber hose connects the tube valve stem to the manifold with hose clamps holding the tube to the manifold. The hose was cut so that the needle valve presses against the inner wall of the steel pipe to start the air flow. Several smaller pipes T off the manifold with aquarium airline tubing and air regulator valves mounted along the airline tubing. The terminal ends of the tubing are then connected to airstones or corner filters to aerate the tanks until the power is restored.
Heating the tanks was accomplished with coleman lanterns lit off under the tanks. They were not that efficient but, they slowed down the rate the tanks cooled off.
Ya old fart (J/K) I ain't old, but I ain't young either
