I'm wanting to set up a large (500-1000 gallon) pond in my basement for my 3 adult turtles. I am totally new to the "pond world" and don't know where to start. I want to make sure I have a great filteration system. Are there any sites you would reccomend to get me started? Are there companys that can help you with this type of thing? I have trouble getting my filters alone to work right, I would be intimidated taking on a project like this (being a young women) and knowing my luck I'd probably seriously mess something up. I am very anxious and want to get started, my turtles and I would love it! I would greatly appreciate any recommendations you can share. Thanks.
