Ok, so I abandoned my project for these guys, and just re-did the old setup. But I did add a nice piece of drift wood, and I have the water filter running over it. There is about 4-5inches of water. They seemed to LOVE it at first. But now that the driftwood is releasing a lot of the tannins, they dont go in the water at all now. I boiled the wood for 2 hrs with some baking soda, then baked it for 45min in the oven, then boiled again for 30 min before putting it in the tank. It has dropped the PH a little, but I compensated with the normal "neutral PH buffer" I have always used.

Here is a pic of the setup Name:  2011-10-06 12.46.38.jpg
