Kaldness Media

There are a few on here, using them in different sorts. One guy is running a 450 gallon system with them but hasn't been on in a while to give us updates, lol.

Hes in hypo right now for about another 2 weeks. then i think he's going to add the rest of the kaldness.
 
Reefwise uses it on their systems and mlreef is the guy with the 450 system. I've recently put it on my display. K1 is huge in freshwater, but other than a few very large reefs I have not been able to find it run by many.
 
Cool... just trying to think of a better way to keep the good nutrient bacteria up instead of down....
 
I'm about 3-4 weeks into my experiment and have noticed zero change. I'm very happy with that as I expected no change. My system was already pretty clean and didn't have testable amounts of ammonia or nitrite. K1 should have zero effect on nitrate as K1 requires air to tumble in most cases, preventing the necessary low oxygen environment to remove.

I know it's just like BIO-Pellets in some fashion... I'm a heavy feeder and feed my Frag Tank all sorts of foods so I need something to help with keeping the bad nutrients down...

This s NOT true. biopellets are a whole different animal requiring completely different water chemistry.
 
I'm still trying to manage the amount in my tank. I originally had so much in there that it was processing more waste then my bioload could produce and the corals were dieing. I now have 1/10th of what I orginally had in my K1 chamber. I also overskim. It's a struggle.

Could K1 potentially be used in a canister filter?

Most definitely. Koi ponds use it this way and it's very popular. The issue will be getting enough tumble and verifying it. This is why I went with a clear reactor.

From a lot of reading, I don't think Bio-pellets and K1 are comparable. Bio-pellets are fuel and increase the bacteria load above the natural balance the tank would form. K1 is simply a home for bacteria to grow. While K1 is an optimized home, theoretically the media itself cannot increase the nitrification capability beyond the nutrient load the tank has before K1 implementation, assuming your Live rock is already sufficient. Assuming your live rock can handle the nutrient load you could remove K1 with zero effect, but again I have yet to test this. Long term testing is needed to verify.

Understand
 
I say give it a try and see how it works for your tank. We all could use the extra data and findings on different setups to help with our own. It amazing that it hasn't gained more popularity. I would never run bio-pellets but I'm excited about using K1. Like Josh said, it doesn't add anything to the tank like bio-pellets do. It's just a home for more bacteria that we already have in our tank.

are these not like bioballls? everyone tossed them out like 6 years ago. why the resurrection?

Bio balls are stagnant, K1 is constantly moving and scrubbing old bacteria off into the water column where it can be skimmed. Only young healthy bacteria can grow on properly tumbling media preventing the bio-ball aging problems.
 
As far as amount of media to use. Here is the math that I’ve worked up for my setups. To calculate for your system, you’ll need to know the amount you feed and how much of that load you want K1 to handle.

Kaldnes K1

Handles 250g(@40% protein) food per 50L of media
**5g per 1L**

Avast Marine mr-10 20" tall (custom ordered)
Height: 22" Overall / Width: 7" Overall
Reaction Chamber: 20" x 4" (4.25" actual inner diameter)
Total Capacity: 283 cu" / 1.22 gallons / 19.6 cups / 4.63L
Kaldnes K1 capacity: bed depth 11.5" / 163 cu" / .7 gallons / 2.67L
volume w/o inner pipe / 136 cu" / .58 gal / 2.22L

NexReef MR1
Height: 16" Overall / Width: 6" Overall
Reaction Chamber: 14" x 4" (3.75" actual inner diameter)
Total Capacity: 155 cu" / .67 gallons / 2.5L
Kaldnes K1 capacity: bed depth 6.5" (estimate) / 71 cu" / .3 gallons / 1.16L
volume w/o inner pipe / 56 cu" / .24 gal / .91L

AquaClear 70
Width: 8" Overall
Reaction Chamber: 3.25d" x 5.5h" x 5.5w"

mr10 20" tall can digest 11.1g food daily
MR1 can digest 4.5g food daily
AquaClear 70 can digest 5g food daily

Display Feeding;
hikari cube is 3g ea (6g feed daily)
autofeeder food storage jar is 30g (takes 4 weeks or more to empty(1g daily)
SPS Coral feeding <2g (every 4 days)
LPS Coral feeding 3 hikari cubes (9g every 4 days)

Daily Display feeding average <10g daily
Daily QT feeding average - currently empty
