Thanks Dave, this is something I knew about, but it is good to be reminded. There are so many little things that can sneak up....

I have pumped circulation through a chiller, but also bubble pipes every 2 inches.

Your comments seem to put more attention on something I have been being casual about. So thank you, I'll make some changes. One thing I found was that the manifold would fill with solution when not in use, and it would take a lot of air to clear it out and produce bubbles from all the holes. I have been planning on remaking the pipes with much smaller holes to get higher air pressure. I'm thinking this will help evacuate the manifold better. I'll put holes in different places when I do it.

That's probably it aerohawk, although the stuff I've seen looked a lot better than that demo. :D

I 'll bet... the video shows a good method. The execution of that method is something else....

Dave,
Well, you've got me thinking. I doesn't look difficult or expensive to use a submersible pump for circulation. It seems it may be more effective than bubbles. Since my tanks are small, I assume it doesn't take much of a pump. I'm looking at this:

Also, do you have any suggestions for tricks to get good circulation? I am also looking at using it in my detergent tank, since bubbles stir up a lot of suds.
