This is a semi continuation of another thread I started earlier this week. To sum it up I am building what appears to be a bio/mechanical filter out of a 200 gallon tank. I cannot put a pre-- filter on my submersable pump to filter out the solids because of the type of pump. I am considering either plastic snow fence or plastic strapping. Which would be better/easier to use? How much of it should I put in? I can get 17,000 feet or 1500 feet off of ebay Should it be cut up and put in bags for easy cleaning or just stick a hose in the tank and flush it out the bottom?

If u wanted to backflush that I would think you could just drain the water that is in it at the time and call it good. Personally I think using that huge thing solely as a biofilter is hugely excessive. I'm not sure the other thread answered the question "what are u using for mechanical filtration?". I can tell you right now if you don't have a mechanical filter in front of that, you will have a giant mess on your hands and your pond will have a lot of floaters.
Here is a picture of the style of pump of pump I have I don't know how to set it up with a pre-filter. From what I have read a 150 gallon stock tank is what is recommended for a 3000 gallon pond. Mine will be 12x17x 3 feet deep with a walk in that will be about 1 1/2 to 2'. I'm not sure how much water it will hold but I'm guessing at least 3000 gallons.

Depending on your stocking level that could be a large enough filter. What I am trying to explain though is that what a biofilter does is provides a place for good bacteria to grow, the type that will consure ammonia and other things that are harmful to the health of hour fish. What they don't provide is effective mechanical filtration. You need something that will filter out the solids. Maybe you can put a mechanical filter in the line between the pump and the profiler? you really don't want to be sending all the fish poop, algae, leaves, pollen, bugs, etc into your biofilter.
Unfortunately that is exactly what I see happening here. I don't know anything about your pond except that you are planning on using a submersible pump, but I get the feeling that you are on the wrong track trying to use that tank to fill with bio-media. Likely all that will happen is whatever media you put in there will quickly get clogged with debris and act like a big settling tank mechanical filter that will be nearly impossible to clean. It could be your pond might not even need any extra bio-filtration for your pond.dieselplower said:
Before you start building anything you need to do some research, think it through and draw out a schematic blueprint of your proposed pond and filter system, post it here or better yet on http://www.koiphen.com/forums/ and get some feed back.
That is too nice a tank to waste on a poorly designed filtration system.
