DIY Pond Filters

Here is a link to a forum where an under gravel filter is suggested.

This also looks like a good idea to me.  One thing I learned is that at first when my fish were small there was very little debris to deal with, but as the fish reproduced and grew bigger it became a problem.  At one point I was cleaning the filter everyday. 

My feeling is that a large gravel bed with 3/4" rock and vermaculture will require the least amount of maintenance and provide a great amount of bio-filtration.   But sometime the situation calls for a filter and these appear to be pretty good.

  1. Thanks for this post. I wonder if pond filters will change much in the coming years.
