Interesting.... they came for koi

Hey... they were not here to sell or deliver a new vehicle. 2291 could be a good number to bring you a win fall. These people actually visited us to select koi and bring them back for their boss.... the man who owns very successful and popular car showrooms in Johor. Saying Hi to you in this picture taken yesterday is Chi Chi..... they all really love koi and never have enough of these nice, healthy and active fish. Thank you for your support.

At long last..... Passion fruits

It was in late 2008 after visiting our customer's place in September that year that we decided to plant Passion fruits in front of our retail outlet. It took a little over 2 years for the plants to bear fruits..... many of them! They are over hanging our big banner which have pictures featuring our customers. Picture shows Mrs HL Ong and her children - it was from them that we got the first saplings and planted them.

Filtration system for Koi pond

Above is a pond built without adequate filtration and totally without any water circulation jets or surface venturi. After having assessed the pond we designed and installed the piping system and built a filter (outside house compound) to effectively support the 10-ton pond. We prefer bottom drain pipes to be elbow-free, but for this one, given the already built structure hindering the way, we had no choice but to use elbows.

We have come across many koi ponds built without careful consideration for their filtration capability. As a result, pond water becomes 'green' and worst still the koi's waste not effectively moving to the filter and koi ended up living in a confined water pond with their own wastes!

For koi to stay happy in a confined water pond, the basic idea is to have their wastes moved to a filter box (it's a pond's refuse bin) as effectively as possible. This is best done by a bottom drain.

If you are not too happy with your koi pond, feel free to get in touch with us.

Green pond water - remedies

Introduced by our Nusajaya customer Mr Dass to Mr Mohd Taib of Seri Alam whose 1 year old koi pond continued to have green water. Mrs Mohd Taib was very upset for having spent the money engaging her landscape contractor to design and build the koi pond and not able to appreciate her koi due to green water.
An assessment of the pond by Kohaku Koi House revealed the following:
(1) Filter ratio to pond was at 25% (at least 5% short) and filter media in the chambers not adequate.
(2) Water circulation not adequate as given the size and the water features built, having one water pump was slightly short.
(3) Installed UV light orientation (across filter water flow is better as opposed to along)
(4) Water surface skimmer not built to clear off surface debris contributed by the nearby plants and shrubs.
Above shortcomings were corrected except filter size to create 30% ratio. Pond water turned clear and koi are now in clear view and Mrs Mohd Taib became our very satisfied customer.
Algae contributes to green water. Algae grows when (1) sunlight (2) nitrate (3) phosphate are present. So shading (Sunlight) of pond helps. Nitrate comes from the koi waste and when you over feed (and not having constant water drip as a standard practice for your pond) nitrate level is raised. However note that you have no control over Phosphate which is present in tap water.
We need a big enough filter box of at least 30%, completely filled with filter media (filter brush, filter mat and coral) and have pond water continuously flowing through the filter media guided by the filter chamber partitions. Unnoticed by our naked eyes, the filter media's millions of bacteria 'clear' the water of algae including Ammonia and Nitrite which are harmful to your koi.
Should you have green water problems, feel free to get in touch with us.

Koi in glass tank

Visited customer Mr Ibrahim who has several koi ponds within his very big bangalow. One of the koi ponds is with glass panel (picture above) where he keeps his medium-sized koi. Very good collection of koi indeed!
Mr Ibrahim prefers to buy many koi at one go and only after keeping them for several months he would then determine where a particular koi would end up - either his 5 feet main pond (20-ton) or this 10-ton glass tank with proper filter system.
The best koi collection in a glass tank I have seen so far..... Congratulations to Mr Ibrahim.

Koi harvest - Ogata Koi Farm, 18 October

Top pic - Overview of natural pond, 2nd pic - rounding up (pond water drained)
3rd pic - Transferring koi to truck with aerated tanks, Pic. above - Harvested koi.
It was a very early Sunday morning, together with 10 over Ogata Koi farm staff and its boss, Mr Manabu Ogata, we headed for one of their 8 natural ponds in several trucks. It was going to be an exciting but a tiring job for these farm people.
With good pace (except pulling the net which was very heavy) and teamwork, it took them 3 rounds of pulling their huge and long net to bring in almost all the koi that had been left in the pond to grow for several months.
It was a real eye-opener to see so many jumbo size koi being harvested. Mr Manabu Ogata was fully satisfied with the growth and health condition of the koi harvested that morning.
The harvested koi were then brought back to be photographed and checked for size..... the biggest for a 4-year old was 82 cm!

Shade with Passion fruits

Can you see passion fruits hanging from the plants above the koi pond?

Visited Mr HL Ong's house (scroll down to refer to post dated 10 December 2007) for mid-autumn festival and was amazed by his great effort caring for his koi collection! Simply fantastic - his biggest piece has grown to easily 60 cm from about 35 cm bought a year ago.
To provide shade for his koi he has planted Passion fruit - a great idea and a first, I think. This adds a touch of class to the whole pond with passion fruits hanging from the plant above the koi pond.
Kohaku Koi House today enbarks on a similar initiative to commence planting passion fruit plants at our outlet with the intention to bring this idea to other customers.

Buying koi via internet

Chiller at work during packing

Above picture shows the 6 koi. Below the plastic bags, ice pack on the right.

After several weeks, Mr Jacky Chan of Bintulu, Sarawak received his koi; happy, excited and a satisfied customer.

It is not that difficult to take pictures of koi now that mobile phones can replace the role of a Nikon or Canon. The only worry is the possible injury to the koi during netting. It is however more time-consuming compared to selling at the outlet. But then, given the convenience and flexibility of computer, a lot of such works could be carried out after operating hours or as and when time permits. So rest assured that you will still get your money's worth. I take the liberty to publish Mr Chan's email received yesterday. Here it goes.......

"Finally, Six quality Koi from Kohaku Koi House swimming snuggling in my pond, a great thank to you, Mr. Ong,

My Koi arrived a bit late this afternoon at 2:00pm (15 minutes delay) but it is worth to wait for my quality Koi. Upon arriving home, I quickly open up the well-packed box with Chiller to lower down the temperature (over at KK House, we use a chiller to bring down water temperature to 20 degree C) all six Koi look healthy and swimming swiftly in my eyes.

It is a new lesson to me too that Koi colour will fade after it was frightened or felt uneasy, especially its black patches on black-based Koi namely, Showa and Utsuri. Thanks God, all colour re-emerged to solid Sumi (black) after some 3-4 hours' rest in my pond.

Wow!!!! I finally got my dream Hi-Utsuri, Showa, Shusui, Doitsu Sanke and Goshiki.

Again, I extend my utmost appreciation to you, Mr. Ong.

Please find the attached photos for more detail, I purposely took them for record for both of us.
I have no objection too if you would like to publish the 3rd picture in your blog, after all, I thank you for introduce all six Koi to me patiently and promptly via email, as well as phone communication.

I guess one of these days I should fly over to Johor to pay a visit to your farm.

It is a start but not end, for Koi hobbyists here in Bintulu.

Jacky JH Chan"

Well Mr Chan, I have said in my reply to your email that I am glad for you. I would also like to thank you for your support, you had been such a pleasant customer!

Recent visit to Wuxi Koi farm, China

Picture shows getting fries ready for culling by experienced staff of the farm.

It's the busier time for a koi farm when culling starts. Koi from Wuxi farm has been selling very well due to its high quality and the huge domestic market. It is not unusual for a customer to travel for 10 over hours by train to pick up Koi from the farm!

We only air freight Wuxi Koi to Malaysia for competition (China domestic demand for Koi is very huge!) and to-date only one Malaysian customer has the privilege of raising Wuxi koi as he ordered them from Wuxi direct via it's website He is Mr AC Ng of Xin Hwa trading & transport.

Log on to for better understanding of our Wuxi farm.

Friend from Sarawak via

Got an enquiry from Mr Jacky Chan who asked about an Aka utsuri or Hi utsuri which he spotted in one of our pictures posted on or this blog site. Unfortunately this piece was sold off together with a Shiro utsuri some 3 weeks ago.

We will soon be sending a picture of another beautiful Hi utsuri via email. He will also be informed on how he could get koi direct from us at a very affordable fee (air freight and import/export permits, etc together with other buyers from Sarawak) as we have regular koi retailers from Sarawak buying koi from us.

Impression of Ogata Koi Farm

A very well organized and big farm. A farm with huge natural ponds (total 7 nos.) to breed very good koi for the world market. These natural ponds are scattered about in different locations and about 1 hour's drive away. Before harvest of these koi, 10 days are needed to drain off the pond water!

Inspected easily 4000 koi and selected about 110 pcs of 8 to 14 inches. These will be shipped over on 8 May and we will commence selling them from 13 May after 5 days' quarantine.

You have to visit us to see for yourself the hand-picked Koi from Ogata Farm.

Trip to Ogata Koi Farm

Have been selling Ogata koi for a long time but visiting it for the first time end April! I didn't know Fukuoka is actually on Kyushu island and not on Honshu. I recall the good old days of Yaohan supermarket promoting fruits from Fukuoka city, Japan. It was Renny, my pond and koi customer from Seri Alam who got the location of this place from the internet. Renny will be travelling with me for his very first visit to a Japan koi farm!

Mr HL Ong and family

For the last few months we have HL and his family visiting us regularly and adding koi to their new koi pond after each visit.

This morning, the son, whose name with initial CK spotted a Sanke with the letters CK across the body and decided to add this koi to their collection. The daughter picked a 14" friendly yellow kawarimono from our newly completed koi ponds. Pictures show Mr HL Ong and family viewing and selecting koi. HL also purchased a salt tester which is useful should there be a bacteria attack.

HL's koi pond has a swing above the pond which makes viewing of koi particularly enjoyable! I look forward to feature his koi pond in my blog soon.
