Ive had this custom made tank for the last two years. It has four levels each increasing in size, starting from the top. Great tank for almost anything. Ive used it as a plant tank, African Cichlids, Livebearers, angels, discus, amazon tank, and eventually used it as a quarantine tank. Each level has a proportioned overflow prefilter before eventually feeding to your own sump/wet dry filter. I am selling the tank itself, sump not included. I forgot to take the measurements this morning but will post them up tomorrow. I know the base of the tank is 28" by 29" and the bottomlevel is just over 40 gallons, and the tank is easily 4-4' tall. I will post all the measurements and total gallonage tomorrow. PM me for more info, or pics. NEVER leaked, or cracked. Will gladly fill upon pick up to be sure. Asking $200.
