      Here's a picture; like I said, the blocks have hardly any coloration at all, just a pale touch of brown. They probably won't darken much until next Spring when feeding resumes.

      This filter design in your pics/ video is interesting. thanks for showing that. I didn't think biofiltration did that much for clarity. I'm confused by that.

      I'm going to make a low profile filter this winter so I have time to get my design right since winter here lasts forever
      Going back to an earlier comment about the flushing design that would have a con of being loud, can someone show me a low profile flushing design or any flushing design that starts out going thru a sieve? Is there a way to shut off the flushing feature so it just runs thru when you don't want to hear it flushing while enjoying the pond? This would allow 50 % crashing water and then 50% submerged with a good channeling reducing cleanout, right?

      My budget is small both on the build and the electricity and I want to get the most ghp with the least head so low profile would be better then a barrel.
      I have a ton of kaldnes in 3 sizes so using it would be cheap for me. Any links or ideas?

      Should I move this to it's own thread or is adding it here with your comments ok?

      03 March 2019 Update:
      For the first time since the pond was built (21 months ago), nitrate has dropped to near zero. That said, we've been getting a lot of rain, plus the fish haven't been fed since November, so how much of that is the shower is a big unknown. The real test will be as we ease into Spring and feeding starts up again.

      If you sense that I remain skeptical, I am. if nitrate stays low on into the summer, I'll give credit to the filter, because everything else has remained constant, but how it's achieving that remains a mystery, but time will tell.

      Not all filters... shower filters included, lower NitrAtes.

      I'm surprised if any do.

      I mean denitrifying filters exist in waste treatment. I just think that if you wanted to do it reliably on a pond, you'd need a big static bed with a pump on a microcontroller that is measuring DO of the effluent.

      You do not think there can be pockets with anaerobic bacteria?

      I don't know enough to say one way or the other. I built this to let the filter tell me what it's capable of. If it can reduce nitrate, great, and understanding how it does so is the end goal.

      To be honest, I don't remember. Ask Zac, who I bought them from.

      Retail: $30 for a 12" x 12" x 2" block or $165.00 for a cubic foot (6 blocks).

      Nguyen365 and kimini I missed seeing you at the San Diego Koi Show.
