Very Cute SMG!
Mike, I don't know what to say about the magic tricks! I'll go have a beer at Carl's and let you know! But if your up to the test here is what I'd like you to do- put the magic cups into the biofilter- leave then three weeks just below the surface so sheering effect doesn't occur. Remove the cups and re-do the whiskey experiment. Here's why-
You again missed something in my last post! Biofilm COVERS all surfaces. There is no longer a raw surface in touch with teh passing water once biofilm coats it. I have some magic proof of my own- put your finger in the drain of your kitcken skin- feel the slime? Touch your teeth before and after you brush- feel diiferent?
The problems your customer was having with pH tell me something was fundamentally wrong with his old system. I think its a safe statement to make when I say I have been to visit over 100 high end show ponds in the USA, UK, Taiwan, Belgium, Germany and Japan. All have one thing in common- they are very stable. So Blishock, Aremia, The dream pond, Kato, Mao, Tsai, Lu, Ballou, Caddock, Stewardson, Waddington, Omachi, Goforth, Langer and Narita all have no pH problems as a chronic consequence of their submerged biofilters! What I'm saying is when anyone, your customer included, goes from a non working to a working system they will be pleased!
I have a few pieces of bacteria house. I'm going to place them in my filters as specimen pieces. I'll put some in the vortex and some in biological section. If I can get some from Carl I'll put some in my towers. I'm interested in seeing the surface change. I think it would be ideal to place lava rock and pitted glass media next to the BH to see if the film changes from material to material. Sounds like fun! JR
