If you were to compare a cubic foot of each the surface area on the K1 would be much more than the bio balls.   #21 fishman Total Posts : 1 Scores: 0 Reward points : 23 Joined: 11/12/2011 Location: Elk Grove, IL, US Status: offline MBI: 0 Pnts MBI Site: UberFrags.net Web Forum Re:Kaldnes Media Experiment Saturday, November 12, 2011 8:47 AM (permalink) 0 Originally Posted by seaweed88 I believe a large difference between bio balls and K1 is the surface area difference. If you were to compare a cubic foot of each the surface area on the K1 would be much more than the bio balls.   Seaweed is correct! The other reason the Kaldness K1 media is different from the regular bio balls is when the bacteria colonize the media it becomes neutrally buoyant and will actually flow through the water with very little effort. The bio balls will lock together and will always float to the top.  The way our systems are set up we basically have a fluidized wet dry as the K1 is constantly being hit with oxygen and water. It is self cleaning this way and also has the advantages of keeping your 02 levels elevated as well as your ph that can become a problem with a heavily stocked system.. Our filters took roughly 6 weeks to fully colonize and settle in. We seeded them with sponge filter bacteria as well as a few commercial products. We like this media as you can build a very simple filter (any size) with a little elbow grease and a trip to home depot. There are quite a few you tube videos on it as well. There is one person who made individual filters out of 2 liter bottles for their tanks. I dont want to hijack this thread but I also dont mind helping out fellow reefers. Please let me know if anyone has questions as I will gladly answer via pm or email.      #22 THEJRC Total Posts : 1006 Scores: 4 Reward points : 555 Joined: 10/23/2009 Location: Colorado Springs, CO, US Status: offline MBI: 210 Pnts MBI Site: Marine Breeding Initiative (MBI) Re:Kaldnes Media Experiment Saturday, November 12, 2011 9:21 AM (permalink) 0 Originally Posted by luis a m I still can´t see the advantage of this product.They are small plastic pieces like bioballs,but light,so they can be tumbled like a bead or sand fluidized filter.

As stated earlier I think this is more of a "we're trying it this way" thread, that said being a fan of everything plankton this really piques my interest as a pseudo bacteria reactor.  As the media tumbles around it will disturb the bacterial colonies thus releasing some into the water column.  Fills my head with all sorts of ideas for alternate setups for the azoox world.

Im running my Brood stock and growout systems on K1 in custom made chambers. Currently running 5Litres on my broodstock, 500litre system. 8-12litres on growout, when fully stopped (have another bank of tanks to bring online) which will bring it up to 1000l and 50g per day feed. With the addition of a good bed of cheato im confident when the system is loaded it can handle the it. main benefit is they dont really need any cleaning or maintainence. media does break down eventually but tends to take about 10 years and is accelerated with UV/sunlight. as meantioned above bioballs interlock and don't self clean.   The Farm i work on has been running fluidised beds for approximately 8years on the RAS (recirculated aquaculture system) trout/arctic charr hatchery. we run 2 large units both 4metre diameter 4.5m deep. heavily aerated we're able to feed up to 100kg per day. can snap some pics if required   #24 GreshamH Total Posts : 757 Scores: 16 Reward points : 600 Joined: 4/27/2011 Location: SF Bay Area, CA Status: offline MBI: 0 Pnts MBI Site: Marine Breeding Initiative (MBI) Re:Kaldnes Media Experiment Thursday, November 17, 2011 5:47 PM (permalink) 0 Originally Posted by TheCoralShoppe Guys, this isn't something new.

Mostly from bacterial populations growing and dying off. In this process with them being moved around, it increases the surface area being exposed to freshwater polluted water. I don't think this thread was meant as an "hey everyone go get this product", it was meant as "hey look i'm trying something different and it works great for high bio load uses" !   I've been using this in system builds for over a decade   We built project Goodfish using fluidized beds filled with these.  We used these at Cortez Marine and I have used them in various other facility builds.  Awesome stuff, but man if you spill a bag, it takes FOR EVER to clean up... a shop vac is a must for this :lol:   #25 seaweed88 Total Posts : 103 Scores: 0 Reward points : 510 Joined: 10/8/2011 Location: Elkhart, IN, US Status: offline MBI: 5 Pnts MBI Site: Marine Breeding Initiative (MBI) Re:Kaldnes Media Experiment Friday, November 18, 2011 4:30 AM (permalink) 0 Do you have any pictures of the chambers you keep the K1 in?

I am very happy with how they are working. Thanks Mark I'm going to set one up this weekend. I watched the link above and followed that link to their store: http://www.ebay.co.uk/sch/tynevalleyaquatics/m.html?_trksid=p4340.l2562 Looks like the K1 media is much cheaper in the UK.   Edit- Decided not to wait for the weekend. While searching for the right sized bottle I stumbled on one that works perfect when using 3/4" PVC... The 1.75L Castillo rum bottles fit right into the elbow! I might add a little bit of teflon tape to make it even tighter but you might not have to. <message edited by Fishtal on Friday, December 9, 2011 4:35 PM> http://www.fishtalpropagations.com/#!home/mainPage "Making captive breeding easier."   #32 reeflover Total Posts : 183 Scores: 0 Reward points : 258 Joined: 11/18/2010 Location: Lakeville, MN, US Status: offline MBI: 175 Pnts MBI Site: Twin Cities Marine Aquarium Society Re:Kaldnes Media Experiment Friday, December 9, 2011 5:02 PM (permalink) 0 I have experience with this media.  Used it in a Low Space Bioreactor for Koi in a large aquaculture set up.  It worked alright, but I wasn't thrilled with it.  Great with ammonia, but not so great with nitrite breakdown.  It depends on the application but I would predict high nitrate levels from this biofiltration a problem for marine applications (most at least).   #33 Fishtal Total Posts : 5467 Scores: 37 Reward points : 2908 Joined: 8/31/2006 Location: Waterford, MI, US Status: offline MBI: 585 Pnts MBI Site: MarineLife Aquarium Society of Michigan Re:Kaldnes Media Experiment Friday, December 9, 2011 5:05 PM (permalink) 0 We'll see what happens.

Well, it wasn't quite as perfect as I'd hoped but I have it in the sump now. I'm not sure if I'm getting enough flow. How long does it take for the media to become N buoyant, a few days or more than a week?   On a side note, a few pieces escaped during install and ended up in the return pump area. They seem to be tumbling pretty well in there with the water flowing over the baffle... would that be a potential area to keep it? http://www.fishtalpropagations.com/#!home/mainPage "Making captive breeding easier."   #36 Scottt Total Posts : 113 Scores: 0 Reward points : 341 Joined: 12/12/2009 Location: , NY, US Status: offline MBI: 5 Pnts MBI Site: MarineLife Aquarium Society of Michigan Re:Kaldnes Media Experiment Saturday, December 10, 2011 12:37 AM (permalink) 0 If I remember correctly, it takes a couple weeks for the media to become neutrally buoyant.  I think the bacteria that grows on it helps weight it down.  It takes a bit of time for the bacteria to grow.   #37 Fishtal Total Posts : 5467 Scores: 37 Reward points : 2908 Joined: 8/31/2006 Location: Waterford, MI, US Status: offline MBI: 585 Pnts MBI Site: MarineLife Aquarium Society of Michigan Re:Kaldnes Media Experiment Saturday, December 10, 2011 12:39 AM (permalink) 0 Ok, thanks http://www.fishtalpropagations.com/#!home/mainPage "Making captive breeding easier."   #38 reeflover Total Posts : 183 Scores: 0 Reward points : 258 Joined: 11/18/2010 Location: Lakeville, MN, US Status: offline MBI: 175 Pnts MBI Site: Twin Cities Marine Aquarium Society Re:Kaldnes Media Experiment Saturday, December 10, 2011 7:16 AM (permalink) 0 Originally Posted by Scottt If I remember correctly, it takes a couple weeks for the media to become neutrally buoyant.  I think the bacteria that grows on it helps weight it down.  It takes a bit of time for the bacteria to grow. Yes, that is absolutely correct.  Plan on it taking the same amount of time as it does to establish a biofilter in the first place.  The only "advantage" of Kaldnes is that it is self-cleaning like a fluidized bed biofilter because it is neutrally bouyant, and will tumble with the use of an airstone or 2.  In effect, it is no different  (or not much different) than an old wet-dry filter, except for needing less space (but much more space than a fluidized bed biofilter).   #39 CableGuy Total Posts : 591 Scores: 7 Reward points : 731 Joined: 8/26/2010 Location: Saint Clair Shores, MI, US Status: offline MBI: 635 Pnts MBI Site: MarineLife Aquarium Society of Michigan Re:Kaldnes Media Experiment Saturday, December 10, 2011 11:02 AM (permalink) 0 I've been running mine for about a week and and most of the media is tumbling but I dont see a change in color yet and there are still some that are just sitting at the top. I also had to take some out as all of it was sitting at the top to start and not tumbling at all. -Adam   #40 Online Bookmarks Sharing: Facebook Digg Google del.icio.us StumbleUpon Change Page: < 12345 > | Showing page 2 of 5, messages 21 to 40 of 94 - powered by ASPPlayground.NET Forum Trial Version
