hi B.Scott

I don't really see the bottom drains as being a possibility. I would avoid that idea. As for the waterfall, I was thinking about some kind of rapids/cascades/rafts? (sorry i can't find the word to that) only to lower the water lever a little bit between part A and B of my pond.

As for filtration, here it is, the Laguna Pressure-Flo

I was thinking to plug one or two of those on a small pool pump.

Don't worry, it didn't even cross my mind

Quote: I think you are perhaps being a bit too ambitious and should seek something more traditional. B.Scott

Now that may be right, but I want it outstanding and uncommon. I have also been given the idea that I could have a koi/goldfish/aquatic turtle on part A, and the rest being for freshwater rays and arowanas. I would have two different filtration systems, one cold, the other warmer.

thanks Scott !!
