Thanks for the links. I think the last point abt not needing mechanical filtration is controversial. Smile

Oh, my goodness, Mark has finally figured out why his koi were bug eyed, namely the high nitrate levels were doing it! Does that mean when I post here once again that I can run my salt up to 1.0% for either salt or koi without getting bug eyed fish he will finally believe me?

Just a question, Mark, think through the data which led you to post the absurd posted observation that salt levels above 0.5% causes bug eyed fish and see if what I say here is not so.........I certainly see no bug eyed fish up to and including 1% salt levels........

I recall a doc, long ago, named Timothy Leary that was another chemist giving advice on the regular use of chemicals to "enhance the quality of life"
The difference was his "subjects" had the option to agree or not.
I believe Ozzie Ozborne, Jimi Hendrix, Janis Joplin and Ron Wood followed his advice..........

Re: [Khoobg] High Nitrates Level? Try This! [In reply to] Can't Post

Hi,

My koi pond is just a few weeks old but have not incorporated the tt system proposed here. Can you make suggestions as to how I can change one or more of my filter chambers to tt since it seems to be proven that it is most effective in clearing out nitrates. Size of pond is about 16 tons including 6 chamber filter each one measuring about 0.9 x 0.9 x 0.8(depth) meters. Transfer pipes consist of 2 3" pvc pipe that transfers water from the top of previous chamber to the bottom of next chamber. Pumps located at last chamber. 1 pump to waterfalls the other to underwater return. Can't seem to figure out how to create less water in one of the chambers to mimick tt system.

Orson

Will it work if i just let the water fill up in the bioball chamber intead of simply allowing the water to trickle down?

Re: [alantang_85] High Nitrates Level? Try This! [In reply to] Can't Post

Alan,

The purpose of a trickle tower is to allow water to mix very well with oxygen (air). The trickling (dripping) affect is the key of mixing water and air. By submerging the bioballs into the water, the chamber becomes a standard filter chamber, not a tt. It will work, but it does not work like a tt. It is the combination of surface contact (bioballs), and mixing of water and air that allow the good bacterials to grow and get rid of the ammonia, nitrite, and nitrate.

Any koi sifu please correct me if my interpretation is wrong here.

Regards,

-Steve

Y not? plant a pot of plants like arrow head, plants as long as can do well half merged water. instead of soil put sand.

There you go more than 6" of sand.

Are you living in SG? If so, go to kallang basin, one of the fish shop there. 10 bucks per 100pcs.

somewhere near kaki bukit ave 1 ( near my work place). selling 9 bucks per 100pcs.

hope this helps.

Re: [johnson lee] High Nitrates Level? Try This! [In reply to] Can't Post

I dont understand why u and the rest mentioned that one must allow the water to drop a distance before reaches the bio ball? I feel that as long as the amount of dissolved air in the water is high enough ( araete the part below it goes into a TT )then it should work then.

I read at biohome website, best flow rate is 5cm/s. I feel that this unit of measurement is more relevant than how many times the pond is cycled in 1 hr. Because every filter esp DIY ones are diff in size and shape.

The fact a lot of SG pple live in matchboxes, the pond of theirs is not big at all. So when we all talk about how many times should a water in the pond be cycled, often I feel that it is not applicable to them as by using a small pump, it might not be efficient in cleaning the dirt and feaces.

Like them I faces this problem, so I designed my own filter , link :http://www.koi.com.my/cgi-bin/koiforum/gforum.cgi?post=32269;sb=post_latest_reply;so=ASC;forum_view=forum_view_collapsed;;page=unread#unread

In this region, many of us do not have the luxury to build big ponds in expensive lands. We therefore built small concrete ones or install ready made small fibreglass tanks. In view of the constraint, there is no or little room left for plants. So installing a trickle tower in such situation is the most logical way to help us to get rid of the nitrates.

Perhaps my design works for s'porean: http://www.koi.com.my/cgi-bin/koiforum/gforum.cgi?post=32269;sb=post_latest_reply;so=ASC;forum_view=forum_view_collapsed;;page=unread#unread

One information that I failed to find in the 8 long pages of this interesting thread is what happened when the TT got dried up, like in a blackout for instance.
I would really hate it to re-cycle the TT all over again due to a several hours of blackout.

Re: [frydaddy] High Nitrates Level? Try This! [In reply to] Can't Post

Hi, This TT topic is sure very interesting. I wish to find out more about this TT stuff.

What kind of cubic area (volume) of TT media to a ton of pond water for example. I have seen TT in the marine aquarium shops, they are as big as their aquarium. If base on this proportion, a 1 ton pond needs an approx 1 cu meter of media if I am not wrong.

I hope the gurus in this forum can shade some light with us.

Cheers

Re: [cwnchong] High Nitrates Level? Try This! [In reply to] Can't Post

I don't know about marine aquarium, but I'm betting that a 1:1 ratio is an overkill. TT is supposed to be more efficient than submerged media, some say that it is 10x more efficient, some even say 100x more efficient (an overstatement, IMHO). That means, you will require less than area/volume to replace your current filtration setup.

Perhaps in an aquarium shops setting, it should be oversized, since the tank will mostlikely be overcrowded.

Re: [frydaddy] High Nitrates Level? Try This! [In reply to] Can't Post

Hi Chip,

I have to agree with you on the efficiency, if it is compared with the fully submerge bio-filter. Becoz our bio-filter are usually too deep. I may be wrong, this IOMO that the depth of our filter ( beside the few inches of it useful surface) has a small benefit only i.e. only good for stabilizing the temperature, but not for cultivating good bacteria.

TT is preferred becoz its surfaces are fully utilized & sufficient oxygen are supplied more evenly in the air. I wish to know how big should our TT be, compare to pond size.

Re: [cwnchong] High Nitrates Level? Try This! [In reply to] Can't Post

Yeah, I can't find good guidelines on the sizing of the TT too.
I suppose we can borrow the rule of 30%, and apply 10-15% of it for a TT setup.

Re: [frydaddy] High Nitrates Level? Try This! [In reply to] Can't Post

hi you seem to be comparing the tt with the tricle filter, if you are. you are right about it being more eficiant i would not go as far as saying 100 times, but one third of media volume which would probably give you a filter quarter the size of a submerged filter, a higher stocking level and higher pumping capasity, no dwelltime,?

the tt and the t filter are totally differant. haveing said that if you could combine the two you would have a perfect fillter?

i too am very interested in this thread nobody seems to know why it works , i personally like doc conrads theiry about bacteria converting the nitrate to gas then being expelled into the atmosphere, if not the gas gets reabsorbed into the water and back into the pond as nitrate, shuerly a simple test for this would be to get a tt that is known to work and encase it so that the gas cant escape if this is why the tt works the nitrate would increase and you have your answer, if this is the case the tt would be more easally adaptobal to differant situations, the more we know the more we can use to are advantage. i have noticed that bio balls seem to be the prefered media virtually unclogable and very open which leans me towards the theary about the gas exchange, also the slower the trickle the better if there was lots of water splashin about comeing in contact with the gas reabsorbing the nitrate,

thats just my opinion the only knowledge i have on the tt is by this very interesting thread

thanks mark

Re: High Nitrates Level? Try This! [In reply to] Can't Post

I was wondering if the relatively high incidence of surface to air exposure of the nutrient (waste) laden water with the bacteria is possibly the cause of the Kaldnes K1 Media's (in the Evolution Aqua Nexus filter) as yet undocumented (?) ability to remove nitrates by the process of expelling ammonia/ammonium wastes directly to gas (NO2)? Especially in comparison to traditional pressurised bio media filters that have no air interface.

Anyone have any bright ideas on the matter?

Re: [BillyBoy] High Nitrates Level? Try This! [In reply to] Can't Post

Great thread. I am learning a lot. Thanks to all that have posted. I do have a couple of questions;

1. Can bio-ribbon, or any other filter media be used in a TT? Has anyone out there used Biohome? (They make some pretty bold claims concerning surface area...and it's ability to lower nitrates from the small passage ways that they claim will create an anaerobic bacteria).

2. Would a vortex filter be a good idea if used before a TT to remove solids and others debris?

3. What type of filter media does a "Bakki Shower" use?

4. What is the recommended MINIMUM height of a TT? What is the maximum width? Should the max. diameter be somewhere around 10-inches, such as a 10-inch PVC pipe?

Thanks in advance,
Mitch

Re: [chiselchst] High Nitrates Level? Try This! [In reply to] Can't Post

If nitrates can be stripped from the water by the aeration process, I would be VERY curious to see how these de-gassing columns would work. One could do practically the same thing by pumping air, counter flow, up through a TT. It wouldn't that diffucult to fab up. Find a continous duty blower might be difficult though...

My hunch says a degassing column would work well. But that's just a guess.

(I work in a large refinery, and we have several processes such as this. I'm going to look in to this process, and see if I can come up with an idea for something similar.
