      I commandeered the content of one of the old baskets for indoor aquarium usage and have this left in dried form. The granularity is not consistent. Also not as "red" as what you have shown -Dave. It looks like my API's laterite though, which retains the granular size/form.
      Please ignore the bigger pieces, they are rocks I used to weigh down the basket content.

      stillwee,
      I believe the granularity can effect the way it works. When I saw the third picture of post 1196 I suspected that what you used was the clumping type of litter. If it does not keep its granular consistency when soaking in the water for a while I don't think it will work as well. Mine looks like Dave Collins first picture after soaking for more than a year. I don't think the color is important as long as is stays in a granular form when wet. I have several types that I have tried and they all have different colors.

      We had gotten some cheap kitty litter (for the cat) that must of been on the bottom of the processing vat. It had a very large amount of fines. Maybe this is your issue?

      Yes, I suspect so.

      This is the sort of litter we should be using

      Yep, Special Kitty.. That was the brand I bought from Walmart. Like BWG said, most likely I got a bad batch with too much fine. It did not clump.

      Updates please Sweetie

      My Planted `Anoxic` system has a life of it`s own which never ceases to amaze me more and more ... tis akin to witnessing mother nature filling a void re every niche created re balance

      The plants will add organic pollution that contributes to DOCs and lowering of ORP. Koi need plants like they do bicycles.

      I ran anoxic baskets for a few years. Always had great readings on ammonia, nitrite and nitrate. Took them out to go a little different direction. Now that these rotary drums are in use I would love to see a set up of RDF to anoxic baskets. And nothing else. Just to really check the efficacy of the system.

      A shower stack with good media does aeration, nitrification, and denitrification

      But requires you to lift large volumes of water a significant height. Which besides the cost of electricity usage, makes it more challenging to winterize.

      Sounds like a PLAN beloved

      BTW, I would never add plants to a Koi Pond given these are simply "hors d'oeuvres" re koi, mine ate these quicker than they could accomplish any `Nitrification` worthwhile benefit.

      That said given studies re `Effluent`incorporation of reeds etc in relation to potable water purification, along with my own 4 yr GF pond experience, I would absolutely recommend a separate planted area in which plants could thrive via pond water phlow thru

      I was thinking about plants being relied on as part of the nitrification/denitrification process. The question I have is what does the nitrification/denitrification process in the late fall, winter and early spring when the plants die back?

      There is no such thing as `Plants`dying back EVER, Algae in all it`s forms will take-up-the-slack, Nature abhors a vacuum

      A whole lot more than `bio` could accomplish at those temps truly beloved we have barely touched upon what nature is capable of

      Bob, I ran 5 of my baskets with out plants and 2 with. The two with plants as I went in to fall I kept them trimmed as they started to die back. And then I pulled those two pots out over winter. I do believe in pulling as much bio and organic material out as quickly as I can so that it does not sit in water below 50 degrees waiting for spring for the algae to break it down. ChiChi might have different temps that allow her bio mass to decompose in the winter months.

      algae ain`t breaking anything down beloved.

      If pulling those trimmed back plants felt like a good idea to you Bob, then go with that, tis all we can do re our current understanding ,no big deal, we get to phigure it out along the way

      I've never been more confused in ponding in my life and want to understand this
      Alga Plantae, beloved is huge in comparison with the nitrification biota species nitrosomona/nitrobacter, hence have a much broader spectrum of parameters within which to optimise their potential, ie less restricted than their inferior bacterial counterparts ,,
