I don't get this. You see on the shelves in the stores these small boxes
that are capable of filtering a 1,000 gal. pond and people are telling
me
i have to build a 50 gal. filter to do the same job. I'm
confused................................

What you see in the stores are small boxes that makers _claim_ will filter
a
1,000 gallon pond. They're full of S***. And pretty soon, that little
filter box will be too. I guess they work if you're prepared to clean out
the filter material every couple of days (and I bet they expect you to use
disposable materials, rather than cleaning it).

The ones you're being advised to build will require a great deal less
maintenance.
