Kaldness Media

Yes it houses Bacteria which is what your system need for the biological process it's gives your system a little boost and help out with keeping your nutrients low

It's pricey though for the media so I see why no one really uses it...

Ebay has it about the cheapest I could find in small volumes, $30 for a gallon and $52 for 2 gallons. Like bio-balls it never wears out. The inital wastewater treament plant testing K1 is still running the same media installed in the 1980s.

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

Cool. I have to take a look... I am also looking at the Avast MR10 since I've used that reactor before with good results

The hardest part I've trying to overcome is the burping of the output tube. Second is that I am injecting and mixing the air/water upstream of the reactor, which creates a pressurized chamber. By itself the pressure is good as it will drive up O2 levels in the tank, but the negative is if the air pump stops even an quality air check valve does not prevent water back flowing into the air pump.

Do you have a picture of your setup or video?
 
Walt I just realized you posted a Video... Thats is cool they way it tumbles in your sump chamber nice work

That looks good...

Thank you. Just like Walt, I'm still fine tuning. I have my test rig for the fragclub 8x8x8 K1 media tumbler running at home as I type. I'm thinking it'll be the perfect place to test K1 as in such a small water volume there will be nowhere for deficiencies to hide.
 
I run a large kaldness reactor on my 440 gal tank (approx 550 gal total). Have a heavy bio load and I believe it helps maintain very low nitrate levels.

John at Reef Imports Hatchery is using on his system and is the person that built my reactor.

How long have you had the reactor operational? Do you know how much media you run and an estimate of how much food you add on a daily average?

That is interesting about nitrates. It would suggest that K1 does actually support a larger population than could be achieved with other means(live rock, sponge, etc) and might suggest removing K1 could cause problems. As I manage my nitrates with water changes, I’ll notice the change as time progresses.

For anyone else following, a short nitrate summary here;

Sweet just received my order in th mail, this 1 gallon is going to go a long way.... I am going to start off with just a 1/2 cup and report back my findings...
 
So it has been a few months since the last post . How are things going with the few active members that were using this ? Updates please
 
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.
