there are several good skimmers. however, they can be pricey. It sounds like you have a tight budget. If I have surmized wrong I am sorry. Look at the AquaC, the Octopus and EShoppes. I suggest searching the different discussions in this forum. There have been several very good pro/con comparisons. I believe the main points for consideration are price, size and location. Price is obvious, I undestand staying on budget is important. Size depends on your tank and sump volume as well as the next item, location. If you need a HOB or submersable. If you get stuck ask questions. Someone will jump in to assist.
