Bakki Showers: Where's The Dirt?

[GazKoi]

Hi Tewa,


You are indeed spot on with you view,i had BH submerged in both my past and present filtration and recently removed it to install in a TT and was amazed at the amount of dust or whatever was stuck on the BH and filter grid!!

I am not saying it does not work far from it i find its a great media and work very very well.

However, when that flush water is turned off and nutrient builds up, the heterotrophs in the water column go crazy. This sysyem has got to have the flush water to work, in my experience.

Interesting observation. If this is true, I should be able to put in a protein skimmer and reduce the amount of flush water?


(Air-driven protein skimmers are relatively maintenance-free. So entire system is relatively maintenance free and wastes very little water).


Never mind, I just saw the "no DOC foam".

Dear Roger,

Have you had any kois with hikkui or have you seen hikkui before? Those who had knows how ugly it looks and how devastating it can be for the owner. I am not going to do an experiment which can potentially harm any fish, and big matured ones at that.


...Yep dtbh, but you voiced your concern, but then again why don't you voice your concern that hikkui was long here before the BS/BH system. Some koi hobbyists who are not using the BS/BH system in their concrete pond, but the conventional system, their koi are also affected by the hikkui disease. That being the case, we should voice our concern and asked all koi hobbyists who are using the conventional system to change theirs or to improve on their system, ie if the system is the factor/problem to it.

Everyone knows hikkui can occur in conventional systems. As such I do not have to raise the alarm as it would be redundant. Those who are using them should know what they have to do. Ask them to change? I hope you are joking. Who are we to ask anyone to change? We are here to learn and share our observations and not to enforce our advice or practices.


...Dtbh, I think you said it right... until such time that this has been figured out by this member.... I think he should have an overall view of his system, where he got his prized koi from, what food he is feeding the koi... before you voiced your concern that it might be dued to this system. (one sparrow doesn't make a summer)

Considering the serious nature of hikkui (on the koi and the owner) it is the duty of anyone to report it. Just like any serious human diseases, the authorities do not wait until they have figured it out before they report it. It is better for whoever is using this system to be on the lookout and to be mentally prepared. We know one report does not make an epidemic but still it cannot be ignored.


...Dtbh, how are all the members be able to tell you?... most, most they are having the BH/BS system for 2 years. Why not direct your question to the right person - MaedaSan, his ponds are bathed with BH/BS system much, much more longer than most of the members.


When I have the chance I will definitely speak to him. Meanwhile there is no harm to be on the alert.

Cheers, dtbh
