A few folks have asked me via PM some variation of 'Isn't a 265 big enough?' The quick answer, of course, is NO!
I view a fish tank like I view storage - crap will proliferate to fill the available space!!!!
So, why am I getting a bigger tank?
1. I am maxed out in the 265 and would like to keep some fish for which 265
is too small.
2. I enjoy the build process more than I enjoy the maintain process - so it's also about not getting bored.
3. I always like to have a major project every year - 2016 it was building a new master bathroom, 2017 a bigger tank.
4. My sons are now old enough to help with a project like this, and that's both a good experience for us and great learning (structural, woodworking, plumbing, fluid dynamics ..... OK, may be that's a stretch).
5. Most importantly ..... just .... because!
