Supreme Aquamaster PME. Well done, Fresh2o. It's off to Craigslist to see if any are still around.
It's sad they don't make these any more. As a chemical engineer, I find the particle filtration media depth in (what would be comparably priced) current filters laughable. In the Aquaking, $0.15 of polyester and $0.25 of activated carbon in a bag would do a lot more filtration than today's 3/8" thick, $5.00 filter cartridge. Moreover, pumping the water into the box (as is done with current filters) is a great way to make sushi out of fry.
Thanks again, Fresh20.
