Ahh yes, I was getting a bit confused as to who or what we were talking about
there (
LOL!).
lori....
I posted in another thread also about the fact that any "above ground" portions
should be insulated; insulation takes care of both cold AND heat...if done properly
and thick enough!! Also plant cover does remarkably well for keeping water
temps within range.... as does aeration (fountains, etc).
A note when installing liners.....be carfeul to NOT fully secure your liner until
after at least 2/3 of the water is in. It must be loaded initially in stages...so
that your liner can "give" or properly setlle when the weight of the water is
applied!!
Also.... wasn't completely following what or how you intended to use the sheet metal??? I'd look long and hard at any use of cut metal (grinded off or not);
would prob suggest a number of other materials depending on exactly how you
were intending to use it!??
