I am getting my tank up and running as we speak...I have about 50lbs of uncured LR in the tank and a 1" sand bed...right now I am looking for a HOB skimmer because I am not using a sump ..so everything is going to be on the tank....Mind you its a 38 gallon tank..and I am undecided which one to buy...it will be off eBay so if anyone has any suggestions please post them......the only problem is ...$$$....I cant convince the wife to spend a whole-hell-of alot on this piece of equip.
