I got this tank from a buddy and modified it, it originally had one of those agitator's, which I think don't work very well. I basically added a 750gph Tsunami Bilge pump, and a Flowrite Pump in and Pump out aerator. Basically the aerator head has an air intake. These type of designs push much more oxygen into the water. Also added weather stripping to the lid to prevent leaks. Originally came with a velcro strap to keep the lid down, I added a bungee cord instead, more dependable and keeps the lid closed tight. Around 10ft of cable on the pump with aligator clips, this tank is very mobile and easy to move around. Also comes with a rubber plug to assist in draining. The dual pump in and out aerator head basically allows you to pull it away from the housing and re-directs the flow of water out of the tank. I was told this tank is 20 gal, I am not very good at looking at something to tell how many gallons it holds, so I would say between 15 and 20 gallons to be safe. Tank is insulated as well. If you are looking for a good bait tank, that doesn't take up a ton of space this one is for you, over 50$ in modifications alone, I think these tanks sold for over 200$ brand new. Believe this was a Weston Tank. Asking 100$, prefer local pickup, might get pricey to ship.
