The backup hood is in the tank, well kinda, a few minor(yea right) glitches in my plan, bought 10 gals, put in the first 5 & not even 1/4"in the tank, not gonna buy 30 gals more of this liquid gold!
My center seam leaked a little, so I will try the circulating method, tilted the tank, made some holes in the bottom of a condensate pump I had laying around & got some 3/8ths tubing & put a bunch a holes in it, eeeekkk the pump won't fit in the tank(made it close to the hood size to try & keep the liquid as little as possible) so I turned the hood the other way, hangs over the top a bit, but the pump fits next to it.
Gonna take a long time, can't keep much of it wet, will have to keep moving the tubing & the hood, hopefuly in a week or 2 all the rust will be gone! Rich.
