Bettasngoldfish reminded me... Once everything warms up, I hope to install a couple vase fountains kind of like the one below, but build it my self instead so I can use a vase that can have a significant number of plants on the top... These will basically be like miniature little "bogs" to help filter the water.

I am going to take a plain vase such as below or plastic container that looks like a vase...

Then, I got some rock tile from StrataStones (http://www.stratastones.net/products/Dark-Ocean-Pebble-Tile.html)... and I am going to face the vase with the rock tile... That hyperlink about the pringle's can (in my previous post) gave me the idea...

Water will come up in the center, with plants in there, and flow down the rock back into my stream. I am very looking forward to doing this, but waiting for the greenhouses to open when they get a good selection of vases. I might end up going the cheap way, cutting up a plastic container, but just curious what the greenhouses will have. I can't wait to get started on doing this. Definitely going to share pictures once done.
I plumbed up through the bottom of Vietnamese clay pots. I used a diamond bit to cut the hole (very long process, but worked), installed a bulk head and hooked the plumbing to the outside of the bulk head. I even like the algae build up on them, and it gave a great spot for Hyacinth.
