Hey guys, I am trying to better the crappy filtration I have at the moment (currently having to rely on very frequent water changes). So I have two questions.
1)What type of commercial filter do you recommend? Is the pet store or fish store the best place to buy it, or is there a cheaper alternative?
2)Has anyone been successfull creating their own filter systems?
I have an approx. 100gallon pond with 1.1 sliders, a ~50 gallon with a small snapper, and am possibly adding another enclosure with a soft-shell.
Thanks for any imput 
Ian
