I just got done unpacking the rest of the skimmer today, as far as the bottom is concerned I really donââ"šÂ¬Ã¢"žÂ¢t see a problem the bolts are 1- Ã"šÃ‚½ inches apart with a 1/8 or larger gasket and it looks like a groove has been machined into it, the acrylic is at least 3/8 inch thick on the bottom as well as the walls of the cylinders.
I know when I had my ETS skimmer the water was always past the gasket area and never leaked out as all the kalkreactors and calcium reactors that I have had in the past.
In my experience it would have to warp and acrylic being a very stable material I donââ"šÂ¬Ã¢"žÂ¢t see this happening although GEO makes a pretty "hot" skimmer(ha-ha)
I will take a few more pics this afternoon to show you all the bottom, but as far as RCgibson is saying from an engineering point of view it is probably 1 more thing to go wrong but from a maintenance point of view it will be properly maintained due to the fact that maintenance has become more ergonomic and easier to perform , not to mention well thought out planning on the drawing board(GEO) before the construction took place
