Kaldness Media

I wonder how these would do on a quarantine or hospital tank? As in, would this provide ample bio-filtration without having to worry about porous surfaces absorbing medicines? Or maybe that's just too complicated a solution for something that is rather simple (hob filter...)

I throw a handful into my QT when I use it.

100% positive, zero negatives in either the pico or the DT. In the pico it handles all of the bioload with zero ammonia or nitrites, WC take care of the nitrates. In the DT reactor the media is a light brown giving visual results it is working, but I had zero ammonia or nitrites before the media. Nitrates have remained the same pre and post kaldnes. If it wasn't for LR ability to house nitrite fixing bacteria I'd consider removing rubble from the sump.

Yup it's been fantastic I have some of this just tumbling in a reactor, my water clarity seems very clean and the best part is everything is happy and growing fine in my system

That is why I run it on my DT. Instead of using a seeded sponge, I seed K1 in my DT and run it in a reactor on my QT. It may not work well on a hospital tank thought. Many medications including copper will affect the bacteria limiting how much can grow, just the same as in LR.
 
Yeah, exactly what I was thinking, if you needed to quick start a tank it seems like a nice way of doing it, rather than pulling rocks from your sump or DT. Regarding the medication and its effect on the bacteria... Well, yeah, any medication that will adversely affect the biofilter will hit this too, which makes sense. Was wondering that given that its not calcareous, if perhaps it would still function with some medications that are typically limited by absorbtion into sand / rock (one of the reasons live rock is not used in hospital tanks, not the only reason, but one of them if I understand correctly?)

Neat idea all around, I'll have to talk to Will about hooking me up with some :) When I have tank improvement funds again... Lol.
 
Video of my reactor setup for long term update to the thread.

Still no negatives to the reactor or media and it works like a champ when setting up a QT.

Josh, So now that it has been awhile do you believe that K-1 can export nitrates? I read somewhere that media such as this stops at the nitrite to nitrate conversion. Thoughts?

Correct. K1 will do nothing (or close to it) to remove nitrates. 120ml of daily vinegar dosing in my tank all but proves it. The reactor is a high oxygen aerobic environment. Most nitrate fixing bacteria need an anaerobic environment, anaerobic denitrification.

The nitrate conversion will still happen in other areas of your tank such as in live rock.

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"
Total Capacity: 98 cu" / .42 gallons / 1.6L
Kaldnes K1 capacity: bed depth 3.5" (estimate) / .26 gallons / 1L

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
Daily Pico feeding - build in progress

How many of these are you running on your DT and how much K1 are you using?

I forgot all about this post :D

The Avast Reactor is the only one on my DT. The NexReef MR1 is for my QT and the AC70 was for a pico tank which has been broken down. I fill the DT avast reactor as full as possible, as shown and described in the video. http://www.chicagoreefs.com/forums/showthread.php/23619-Avast-K1-media-reactor

The QT reactor gets a varied amount of media, depending on the bioload. I simply open up the DT reactor and scoop out a couple cups into the the QT reactor, then refill the DT reactor with new media. I drop the QT reactor onto the QT, add a MJ1200 feed pump and luft pump to supply the air flow. It's the only filter I use on QT and it has worked flawlessly to date.
