20 gallon tank. Bought new (expensive) hood &light. Extra bulb, pump& filter and LOTS of replacements (were $10/box!) Heater & thermometer, fake plants, decor, lots of water conditioner drops, net, slow feed vacation tablets, 2 cleaning buckets and gravel cleaner suction. Cleaning scrubbies. It could use a gravel top up as some of the bag broke. Other than that you wont need to buy anything! Selling because I havent been able to set it up in this place and its time to thin down. My loss is your gain. Priced for fast sale. Shelbourne McKenzie area pickup.
