I am selling my large sump rated for 200 gallons. The HOB part of the sump will not fit on my new tank. I bought this sump from ebay for 250 dollars. It also has a pump that I bought for 100 dollars. It was used for about 3 weeks until I got my new tank. I will sell the sump and pump for 200. The HOB part is cracked so you might need to buy the new overflow part. If your tank is drilled then theres no problems. Let me know. Also would trade for canister filters for over 300 gallon
