We purchased a used waterfall bio filter and is there any precautions to take before using in our pond. I developed a DIY filter and it cleared up our pond and now we are on to the next step in the rebuilding of our fish pond. We are really excited about this water feature and got a good deal on the bio filter waterfall off of Craigslist. So, any info would be greatly appreciated. I included a photogrpah of our pond.
Thanks!
