Paul,I received all the parts to build the small diatom filter. This one will be rather expensive because the "frame, supports and base" will be 1/2" acrylic sheet. One square foot of the stuff is about $25.00 and each filter uses one square foot.
This one is just for me to experiment but if I ever made any more I don't think I would use acrylic just for the cost. But I like it so much better than any other material and it looks like jewelry.
What about utilizing composite exterior facia board for the base it is plastic type material if you plan on making many?
