This tells you how to convert a aqua tech 30-60 but all you have to do for the 10-15 is use the corresponding penguin model.
You just need the biowheel, bracket, and bearings. I am in the process of converting a 30-60 atm. I have all the parts except the brackets which I am waiting for a LFS to get in.
