Re: NFC: Aquariums

You could always make a concrete tank.  Use concrete framing and use the
plexi for "portals".  You have less viewing area but can hit some obscenely
huge capacities.  Obviously these things need to be built right on the
foundation of your home or garage so it is a basement project.  But imagine
having a 1,000 gallon tank.

I have a 135 gallon tank and really I've been disappointed.  The dimensions
are all wrong for having a nice sized community.  The tank is too tall so
the surface area / volume ratio is poor.  Not enough territory for each
fish.  And truely BIG fishes can't turn around.  I had some gorgeous red
belly pacus that I had to euthanize because they got too big for the tank.
I'd like to try that again with a concrete tank.

There is some good info on constructing concrete tanks if you look around on
the web.  google.com is my favorite search engine.
