I disagree with you there young fellow.. the bubbles you get with vinager are totaly different than salt water.. the bubbles from vinager are short lived and low surface tension, and what they are doing is imploding along the sides of your skimmer because they cannot maintain the bubble. this implosion is the same as cavatation and causes little tiny pits in the size of the skimmer scale, hence cleaning it. but this cleaning action is two fold.. first you have the implosions knocking the scale off the sides, then you have the acidic power of the mixture desolving it. it goes crazy when ou add more vinager as it start fizzing (just like when you have a viniger water mix they you cleaned a lot of pumps with so it is saturated with Ca and you add more viniger to that.. fizzes right up.

Slightly longer answer: Generally speaking, you can't, you just won't get adequate foam fractionation (for the reasons stated above). However that said, there does seem to be such thing as a FW skimmer, think they are run on ponds in areas where the water is so insanely hard that basically you can get foam production.

are you thinking about a surface skimmer?

No - I was thinking about an actual protein skimmer. I saw a company making them a few years ago. They used ceramic based airstones for the smaller bubble sizes and basically compressors instead of airpumps. Other than that they looked more or less identical to say the old style countercurrent skimmers. I went looking for the link but couldn't find them so maybe they weren't viable. Did find a couple skimmers that worked on a slightly (but not altogether) different principle on a couple Koi sites.

Thought I read somewhere that Tanganika water is hard enough that protein skimmers would work on it. I don't remember where I read that though so who knows.

The short answer remains the same. You're not really going to get a protein skimmer intended for saltwater to work on a freshwater tank. I can't really think of an application where it would be really beneficial anyhow, it's not like FW isn't easily managed with water changes.

just through in some melifix it will make the skimmer skimm and it is good for your fish. many very large lakes have a salt content to them Profict example is lakes manitoba and lake winnipeg. Both lakes are in lake lakes but are concidered inlane seas you can smell the salt on the right day. The sand flies are bad but they are attracted to the salt that is on you after you go into the water. You can find quite a few clams that are found in sea water they have adapted to the very low salinity of these lakes. I my self have never measured the salinity of the lakes. Is there anyone that will check it out in the summer???

Schuuran use to make a FW protein skimmer.

Yup. That was exactly what I was thinking about when I first read this thread:

All a pond skimmer does is clean up the surface of leaves and other debris before they sink to the bottom and decay. No foam or skimmate are produced.

Umm did you click on this link posted above: http://www.koicarp.net/filtration/pr...an_sander.html ?

You may want to go back and do that.
