Wow cool setup...one question though your turnover rate is nearly 2.5 times per hour this seems awful fast...

hi andy

yes this turnover rate is much faster compared to conventional systems. I would really like to turn it over three times or more if i could afford the electricity bill. The quicker the turnover rate the quicker the ammonia and the fish waste is getting broken down, thus the koi cannot smell their own waste which improves appetite. When fish wste is collected it sits in the bottom drains or filter chambers until its flushed. most people will only flush once a day maybe twice but the same water passes throudh the bottom drain hour after hour, so the koi is still able to smell its fish waste and this is where bad bacteria grows best. Unless stand pipes of conventional filters have airstones placed in them with an air pump that is timed to turn on every hour thereby flushing the chambers and the bottom drains every hour the scent of the fish waste will remain in the water. that is why i think a quick turnover rate is important (of course you must have a filter that can take up that turnover rate).

Hi Hong,

Greetings from Brunei. I quite agree with Andy on the super fast turnover rate for your Baki Tower. I could understand the need for fast turnover for conventional filter systems where you need to filter out solid waste materials but the whole concept of the Baki tower is to allow aerobic bacteria to convert wastes to less harmfull nitrates and for these nitrates to be taken up by plants or naturally accuring algea in the water. If the water flow is too fast through the filter media where the nitrobacteria resides, conversion will be difficult as the bacteria will be dislodge from the filter media.

I have two home made trickle tower and my turn over rate is 1.5 times. My water is very clear and I have no problem with ammonia as this is a gas that will dessipate into the atmosphere.

I could be wrong, Maybe Baki Towers works on a different principle from Trickle Tower.

Does smelling thier own waste really improves thier appetite?? Huuummmppp, this is new to me. I wonder if that can help me make my kois grow faster. maybe I should shut down one tower and increase the waste in the water. Do you have any reference to articles that I can read on this? very interesting.

Cheers

Hi bukitbunggakoi

yes bakki showers are very different to trickle towers the flow rate is much higher. Secondly Bacteria washing off depends on the media surfaced used, that is why bacteria house is the best media used in a shower. it will do the comple nitrification process and degas nitrates to very low or zero levels. The faster the turnoveer the better. Last of all please read my post carefully i said that the fast turn over rate will reduce fish waste and the smell of their faeces and hence increase appetite. I am not quite sure what you are on about, increasing waste in water Crazy

Hi, I'm a bit confused about the difference between a the TT and the Bakki shower other than the flow rate. What kind of media is used in it? Im planning on making one for my future pond as well but not sure if bio balls will work.
Thanks ^_^

Re: [mashimarojkt] Bakki shower pond in Aust [In reply to] Can't Post
The big difference is the media. TT media can be Sponge, Jmat, Bioballs, Lavarock..., and the list goes on. Bakki Showers rely on a ceramic media called "Bacteria House". It is much larger, heavier, and shaped like a bunch of cylinders. The bacteria live IN the BH media as much as they do ON its surface, so they are not easily washed away. The large surface is somewhat porous like pummice which allows the water to penetrate to where the bacteria live (in the "house"). Because most of the bacteria are not on the surface high flowrates are needed to allow sufficient water contact with them so they can digest the waste and degas the CO2 and Nitrogen.
You can read more about them on Momotaro's website.

Thanks for info, larz1. I too am planning to build a Bakki Shower pond, and need some clarifications from experts like you.

1. Do you need to regularly clean the BHM of algae build up (see pic)? Or just leave alone as per its maintenance-free claim?

2. In our tropical region, is a mechanical or pre-filter needed? Or straight from the bottom drains into Bakki/BHM be good enough like in Japan?

Re: [GERRY888] Bakki shower pond in Aust [In reply to] Can't Post
I'm no expertBlush, but I'll give my opinion anyway.
I would use a vortex settlement or at least a settlement chamber ahead of the B.S. Occasionally draining a settlement is an easy and convenient way to keep the media free from detrius buildup and flushing old water out for fresh water exchange anyway. Most B.S. systems use a 10% daily water change as part of the regime.
Momo uses shade to prevent algae buildup, and that is the way I would go too. A number of good pix are found at TEWA's website;
http://www.tewakoi.com/Products.htm
I would suggest getting more info from TEWA and some of our members in Singapore who run B.S. systems in tropical climates (RogerMoo, DTBH). They can advise you more perfectly as to the specific requirements for a tropical environment.

Re: [larz1] Bakki shower pond in Aust [In reply to] Can't Post
Is there any way to make a DIY of this? I have done some searching and did not find anywhere to buy the bacteria house, can I buy it without buying a whole system, if so does anyone know where? My pond is quite small so I dont think Id need to much, but it definitely seems like the perfect filter.

Thanks

Re: [larz1] Bakki shower pond in Aust [In reply to] Can't Post
Yes that is quite expensive. I am wondering if I could buy some of the media but use my own container rather than pay 1000 for anything. Would this be possible? It seems as it should. One more question, does anyone know how much bacteria house media I would need for a 1000 gallon pond?

Thanks

Re: [koineedtoknower] Bakki shower pond in Aust [In reply to] Can't Post
According the their website 100kg is good for up to 5000 gal. With a smaller pond you need to oversize a bit so I would go with 25-30 kg minimum on a 1000gal pond. I've seen several DIY postings using milk crates or someting similar for the media trays stacked one on top of the other. The design is basically the same as a TT only with BH media and higher flow rate. BH media in a 1000 gal pond would need roughly 2000gph flowrate. Someone more experienced in your locale may be able to give you more detail as climate can influence the fine points.

Hi, I am really interested in building a bakki shower for my future 3000 gallons pond. After reading its results and how great it works as compared to other filtrations. Now my last question is, is it possible to just build the bakki shower system and not other filters?
Thanks ^_^

Re: [mashimarojkt] Bakki shower pond in Aust [In reply to] Can't Post
dtbh is performing a test on BS/BH right now, and only recently switched over to BH without prefiltration. Once he has finished thoroughly running all of his tests for an acceptable period of time I'm sure he will post his results on the forum.
In the meantime a little food for thought.
There are many who use BS/BH systems without any other type of filtration, not even a sediment chamber. Others prefer to use settlement in addition to BS/BH. I don't have this system myself so I can only give my opinion based on common sense.
One of the drawbacks to BS/BH is the fact that they recommend 10% daily water changes. In most cases 5% or less is sufficient but if you have a large fish load and feed heavily you will need to stick to the 10% number. If you are going to have to do water changes anyway, why not take advantage of the settlement chamber to remove old water and debris at the same time as part of the water change regimin?
As I said, just my thoughts.
