Pond Supply

I just built a 750 gallon pond and I am on a tight budget. As many people know a good filter is usually about 0+ but I don’t have that kind of money to spend. I found online a do it yourself filter on youtube. I wanted to know which would you think would be more effective. Here are my two choices, a DIY filter made out of a Rubbermaid container or this store bought one for 0 for a 1,000 gallon pond. My goal is to get one that needs minimal cleaning and keeps the water clear. I provided two links, one of ebay and one of youtube.com. If you don’t want to use the youtube link just go on youtube and type "diy pond filter". For ebay type "pressurized filter 1000" and it should be the first one on e-bay.
