I may be wrong but i've only heard of K1 and K3. No such thing as K2.
I'm working on the sump plan for the 240g and looking at Kaldnes.
With a 75 gallon sump and assuming I need between 40 liters (10g) and 50 liters (13g) of K media, is there any disadvantage to going with the K3 on a larger sump set-up?
K1 - K3 side by side
I can'f find any images of K-2 but I think it is like the K-3 minus the outer ring. K-1 = 1 ring; K-2 = 2 rings; and K-3 = 3 rings.

I think k3 is mainly for ponds I'm sure I would work. But I think it was just made for larger bodies of water
It is definitely marketed heavily for Koi ponds. There is not much difference in cost between K1 and K3 so I am pondering the idea. I just wish I could find someone with first hand experience with K3. Would it be a better choice for 300 gallons total volume or is it overkill beyond measure? I'm of the mindset you can never over-filter. My concern is the larger size of the K3 and if it would bind up and not produce the circulation needed for a proper moving bed filter.

The smaller media will have more surface area per bulk volume of media.
Josie deals with both they would be more directly involved with this type of info.
Thanks Timmy

Greg, I have talked to some pond keeper years ago that used K3. They used a 55 gallon drum about half to three quaters full of media and a big pond pump just to turn the media. This was used to filter a 2000 gallon pond.

Thanks Wes - looking like K1 is the right choice.

Hey they sell k2 on ebay. I have a few liters of it. It is just little bigger than k1
You won't go wrong with k1. It has more surface area than k3. I was thinking about using k3 in my sump but I went with k1 instead. I'm using about 48 litters in a 80 gallon sump

Placed my k1 order with Josie today. Thanks to everyone for the input.
Greg
please be sure to update us on how it is being used with the sump.
I ended up making a screen of layered egg crate to prevent the k1 from moving into other sump chambers, hoping the flow from my tank drains, and a large airstone will be enough to spin the two gallons worth of k1 I have.
what pump are you using im ordering all my stuff now too for the 240g and i have 80g sump not sure what flow rate to go for im getting magdrive i think
