The weir in my skimmer appears to be some form of liner wrapped around a
piece of styrofoam. The liner material is flexible enough to allow the weir
to lean into the skimmer as much as needed, and yet float so only a small
amount of water comes over the top. They also built by folds, some form of
accordian type sides to force all water over the top. This allows the weir
to act as a door, closing the skimmer box off for cleanings.

Do you have more information on this weir?

Making the skimmer box is not a problem, and the use of the marine
plywood
would probably work well. The problem is that you want a weir that is
floating or spring loaded so that it is pushed over by the water trying
to
get into the box, making a very thin layer of water be skimmed. As the
water level in the pond fluctuates, the weir needs to be able to move
with
the water level. A thick layer of water entering the skimmer will not
produce the desired skimming action.

The cost of the skimmer and filter box are expensive ~$500 or more.
Has
anyone seen plans to build one? Any special concerns??

Thinking of using either external quality (CDX) or marine grade
plywood
and
then covering with liner......comments. Expect the pond to be 6 ft x
8
ft
or so and 18-24in deep.

Thanks Daryl
