1. As the above implies, I have a 15k-gallon water-catchment tank. It is roughly 7ft / 2.13m tall, corrugated steel set upon the ground/Earth, lined with rubber, open-air top covered in a PVC tarp, with a few PVC pipes (extending thru the cover, one into the water). 

See attached photo.

I am wondering if this tank might be suitable / useful if setup to use as a reverb unit. If you have any insight, I would appreciate the guidance very much.

I have a thread on Twitter for more info: @geneticeffects
