Yes I noticed all the things you said and I might do another rendering soon.
My fish tank, despite its medium to large size, 33 Gal, does not use an
undergravel filter but instead uses and AquaClear filter, this is the
waterfall you were mentioning. I don't think I will render this because A you
can't see it from this vantage point and B I like the reflection at the
surface of the water the way it is. As for the tank being made of 5 sheets of
glass, I know this and thought about doing it that way but I went for a simple
box differenced box instead, I might try the 5 plates and see how it looks.
