Hi I have to redo my pond in the spring. Its a rubber liner and the walls
are moving in, probably not built in the best way in the first place. Where
can I look to learn more on how to properly build a pond.

Hagar,

Here are a few I used.

Second question,
What type of filter. Where can I go to read and learn about filters? I've
been using a sponge type filter and cleaning it weekly, are the biological
type better, less maintenance. Any help is apprecicated.

I have found the key to a clean pond is LOTS of water plants and very
few/small fish. I'm only using a pump (for my little waterfall) and
prefilter. That's it, and my water is so clear I could toss a book to
the bottom of my pond and read it from up top.
