It's my 4.12 gallon rimless. They are both AquaTop high clarity tanks and they are both have silicone work that is cleaner than the ADA 60P that I just received. I agree with somewhatshocked, been dabbling with ADA\/GLA\/Mr. Aqua over the years but these AquaTop tanks are stunning! From the packaging to the final presentation, these new tanks are tops with me.\n\nLove to hear this about an American company (although the tanks are made outside of the country). Just means cheaper, high-quality tanks for us. Been eyeing the 7g cube and I might have to pull the trigger after hearing about the silicone work.
