Great article, thanks for sharing!

With 1:1,618 as a ratio for a single focal point... what would be the ratios for 2 focal points??

Well written article, thank for taking the time to post it.

Figure the distance from one side of the tank to center your main focal point. That becomes your new 'side' to calculate a second focal point.

Optimally you would have them toward opposite sides, rather than having them both shifted to the same direction.

For example, in a 5' long tank one focal point would be centered 27.5" from one end of the tank. The other would be centered 17" from the opposite end of the tank, and would be a secondary, rather than a primary, focus.

If you have a large enough tank and are able to work in varying levels such as hills, then it may be feasible to center the secondary focal point 17" from the first one.

This article is great, thank you. Where can I find information of how to build different height levels? With what material? Not a round hill made of gravel, but more as a platform with grass about 3/4 up frim the bottom, which ends with a steep cliff down to lower ground? And with a cave in the bottom?
How can this be made without gliding/floating away?

Thanks!
