I've used the canisters from Fair Radio a couple of times. Even though
dented, I was able to make them work. Make sure you get an inflation tube as
the fitting on the canister is non-standard. With one canister I could fill
a 4 ft. balloon.

The canisters do get hot and the residual calcium hydroxide scatters in the
water. Not exactly something you'd want to do in a nice pond. I would
recommend making a simple metal reservoir with a couple gallons of water
that you can dump the hydride into. The reservoir could be immersed in pond
water to keep the temperature low(er) but would contain the chemicals for
disposal later. I did this with an old barbeque grill size propane cylinder.
