My largest is an 800g and I looked everywhere trying to find any tank larger than the typical 210 and below. A couple helpful bits I found:
- There are a ton of geezers in the PHX area that like aquariums and they almost always have some xlnt tanks on CL in the region
- There are several CL amalgamators, among them is "search all of CraigsList"
- I often logged on to
https://giantaquariums.com as he reposts a lot of CL ads. He also posts ads for a LFS in or near Houston, TX that's spendy but usually has an array of nice tank possibilities
- I eventually put an ad on CL myself stating that I was looking for a large tank of roughly 1000g+ ...and then I got lucky.
