I would like to weld a rebar
grid (4-6 inch spacing) together and
place it on the plant shelf so you couldn't see it really unless you are
right on top of it. I would make it in sections
so I could remove it for maintenence. It would satisfy my wife's anxiety
to
know the grid was there and the water would
effectively be only 6 inches deep in case one of our grandkids or
neighbor
kids fell in. We have no fence and our yard
is open to a public greenbelt area which kids use all the time to play.
Is
this a viable alternative? Should I paint it with
epoxy paint to keep the rusting metal from fouling the water? Would the
rusting metal harm the fish or plants?
Sorry for the long post, but I need some help with this one. Thank you
kindly for time and thoughts.
