Put together a protein skimmer out of two bottles and a wood airstone to be put into the back of my biocube 8.

basically it's driven by an airstone and the foam gets pushed up and out by the rising bubbles. it's not the most efficient skimmer but the only thing i specifically had to buy was the wood airstone.

may not be the prettiest or most efficient...but hey, a Coke skimmer is better then Skimmer...I think I'm going to have to give it a try for my AP24...how does it sit in back? just float in there?

i have it braced with some rock rubble so it stays put and at the right height. it was a bit of a squeeze to get it into the chamber but once it got bellow the top lip there was enough room. the rising bubbles do well to suck water into the chamber and after running for about 7 hours it's pulling some nice brown gunk out.

That is a neat lil experiment...I m going to try it. Does a skimmer pull out the salt in the water to though??

I've been toying with the concept of the coke bottle skimmer and have two questions,

1. what size air pump did you use?

2. How did you do the connection between the two bottles?
