The ones I've seen, the frame is actually aluminum, so rusting would not be a problem. I was actually thinking that the frame would be great for growing vining flowers on, although it would take a couple years for the plants to really fill in.xAbD said:I've seen those on various sites also. While I would have the barrels hidden behind the garage, those tanks are probably much bigger but also much uglier! :lol: As I say, there's a need to balance the inconvenience of a movable pool with the space lost by barrels/tanks. My main concern about those tanks (other than comments from my wife!) is what happens when the metal supports rust away? Are the tanks actually strong enough to support the pressure of water on those sides? They metal frames may be simply for protection during shipping/moving during construction.
Anyway, another possibility! Thanks! B)
Your typical filter design requires the top to be cut off the tank, and once you do that, I do not believe it would be able to support itself without the cage. That's a clear advantage of the barrels -- I've cut off the tops, and even cut them in half to make a 25-gal filter for my first pond, and they still maintain integrity to stand on their own. The two barrels I'm using now have the first 1/3 buried in the ground, which puts them at a nice height beside the waterfall. There's no end to what you can do to dress them up or hide them.
