**Caveat** I know NOTHING about fishtanksdirect other what I've read on the web
However if you feel like you were scammed, you might consider looking into your states consumer protection statutes. I'm not suggesting you go at them guns blazing with lawyer in hand; but I thoughtful well written letter referencing with specificity your states consumer protections laws can do wonders
I just think given the insane amount of money we spend on our hobby we should keep in mind that we have rights as consumers. No one shelling out the money needed to buy a large tank from a reputable commercial supplier should ever walk away feeling like they got cheated.
