I went to Tank It Easy for the first time today.  They have a nice selection of livestock, regular set hours, and a beautiful set-up which they just expanded.  The expansion was still in the final stages of construction, and the store was nearly spotless!  Tom was very helpful and attentive.  I got the impression that their main business is installation and maintenance, but they also appear to be a very nice LFS as well!  I will definitely be going back soon!
