I fell hard for the idea of an 18" tall 65 gallon All In One. Clear for Life makes them but neither PetCo or Petsmart will special order one even if I pay for it right then. Plus I am not a fan of euro tops, the design of their AIO flow, or their placement on the back. Hunted for a used one for 3 months figuring price would forgive a lot. Nada. Commercial driver so my shopping area is a 1000 mile plus corridor between Scranton, Pa and Fargo, Nd with St Louis, Il to Scranton as the back haul.
