Runs perfectly. Has a little surface "skimmer" that attached to the filter intake. All filter media intact, it was cleaned when I moved the contents into a larger tank. Heater included. The only flaw in the tank is in the hood. When I had it running I placed a heater the rear compartmentand the cord offset the lid a bit. Just a tiny bit. Please contact me for more details or if you have any questions. I do not have the original box or instructions. I am in Arizona. Am willing to ship but it will be expensive.
