well I will answer my own question on the chance someone else would like to know this in the future.
I was told by the PetSmart manager to go to premier aquatics. I was surprised there website looked to be salt only. Great place, great people. They had several tanks. Not even close to the same price as PetSmart but, well you hope to get what you pay for.
I have a 180 coming with stand and canopy.
Just need to find the hardscape next…
