I am glad to hear that your open-minded enough to know that you can still learn a lot even after ten years!
I do not know the exact model name or number, but I have used the ocean clear filter with a pleated mechanical cartridge quite successfully for turtles. Iwaki is a good brand of pump. Between these two parts you are looking at $300, but they are far superior to a canister filter, and will last a lot longer.
I included the web site below for ultraviolet light. Mercury vapor bulbs are capable of providing the heat and UVB necessary. I personally have products from this small company that is dedicated to providing quality lamps to reptile owners, and not to their profit margins. Externally ballasted Mercury vapor bulbs are better than the internally ballasted bulbs currently being sold and pet stores because they last a lot longer.
