I
like Koi and goldfish, always have. So, I snagged a free
hot-tub
shell from craigslist. It's 7' x 7' , and I estimate it
weighs
somewhere around three hundred pounds.
For
the filter I scavenged / dumpster dove a dishwasher pump, and mated it
to the existing 1 1/2 inch pipe for the tub. First, I tried
putting the filter on the intake, but it clogged to easily.
Then
I went for a biological style filter, made out of a 5 gallon bucket,
some sand, and a pillow (the poly-fil stuffing was cheaper in a pillow
than in a bag)
