Hey guys thought that I would give an update since this thing is finished. Ok here goes. I made a DIY filter for this thing. I bought a 6ft dia cattle tub at the local farm supply store. It is 2 ft deep and rated at around 350-400gal. It costed me $150. For the filter I bought a large household water filter for around $40, some pipes and tubing $10, a 1200 gph pump $50. I also bought a heater $20, some filter media $10, and a thermometer $1. So this project costed me around $281. I will put some pics up too. Enjoy.
