Where in the world did you get them from....flee market finds?I don't think these are made any more. I found limited information online....
Nice finds,hope they work.I bought a couple of really only tanks and it came with them...
Back when I was just getting into saltwater I bought a Supreme Skilter -hang on power filter with built in protein skimmer.I haven't seen one of those in years....probably for good reason.Our competitor back in my LFS days sold those, they are just terrible. Besides being a shock hazard, they sound like an iron lung if the water level drops, and you have to dick around getting the intake tubes full of water to start the siphon (there should be a cap with a wooden stick that goes with them)
They worked moderately well if you added a lime wood air stone and air pump but didn't skim well enough on their own. But at least they used an Aqua Clear type motor design.Back when I was just getting into saltwater I bought a Supreme Skilter -hang on power filter with built in protein skimmer.I haven't seen one of those in years....probably for good reason.
