      Thanks for all the info... I have a couple of questions after going over this with my husband. Right now we have what I believe is called BioFalls. It's a big container at the top of the waterfall. The water is pumped from the skimmer and fills the bio-falls from the bottom. The Bio falls are filled with some kind of media in sacks, I think it might be lava rock. First question is can we eliminate the Shower Bio-Filter and just use the existing BioFalls? Perhaps use a different media? I assume that the volume of water exiting the S&G would be sufficient to run the falls if we size the pump correctly. In the current set up, a 3500 GPH pump is needed to lift the water from the skimmer to the falls and get sufficient flow. But as yet, I haven't thought of an esthetic way to get the water from the Shower Bio-Filter into the falls. AGain, I sure appreciate all the advice here. Thanks . -cj-

      You could turn the biofalls into a small moving bed filter, only because it’s already there , but it is probably too small to be very effective. The Aquascape industry calls them “Bio” filters , but they are not very efficient at Bio filtration. Read up on the difference between shower filters , and moving bed filters.
