I have a 20 gallon tank (see photos attached) and as you can see it's getting crowded. So I was looking to either switch with someone who needs a smaller tank or try to sell and upgrade. The exact size of the tank is 24"W x 12"D x 16"H I would be willing to give just the tank and cast iron stand for $99 or I can also include gravel, air pump, air pipes, air stone, water filter and filter cartridges, and even double sided background for extra $69 which would make this 20 Gallon tank "Just add water" If you do take everything and pick up fairly quickly, I am willing to throw in the tank starter chemicals and pH balancer I'm just trying to raise some money for a bigger aquarium and if you have more questions, I would be glad to help. Thanks !!!
