Thanks for commenting my pictures Krinedawg : )
The material you can see is a sponge attached to the intake of my hangon filter, more than doubling the filtration capacity. I hope it will be covered in plants some day giving even more filtration and being invisible. If you check out the site for the 2009 aca convention there is a link explaining how they work and with great picture ideas, Swiss something?
