    Have heard some sifu saying green water good for koi...I have try two weeks switching off uv light but the water turn to cloudy a bit...when I turn on back the uv in 1 day in turn to be crystal clear..is the cloudy is part of the process before the water turn to green?

    Green water is supposedly one of the best ways for vibrant colours especially the hi of the koi, that's why colour food is primarily made with spirulina, which is an algae product. Mudponds also have green water, though of course in which case the clay itself also adds to the benefit. (In my own humble opinion)
    If I'm not mistaken, the water turning cloudy is part of the process, then it will soon turn a very light greenish then to a nice dark (but not too dark) green.
    But this is quite a big sacrifice to do in your display pond, usually the process is to have a separate tank/pond with green water and choose some of the fishes that you wish to groom in green water.

    Kktan....dont understand whats u saying...

    James...if im telling who then I no need to quote sifu right? Hehe

    Bro ca..tq for explanation....I have 3 ponds and I can have 1 to test...hehe...since I got most of koi doitsu, im thinking other method to maintain and sustain the color by not just depending on color food and chiller..

    I do have a hard time turning to green water as I do not even have UV lights. I was thinking this summer i will pound spirulina koi food to tiny bits and throw it in the pond and then dont clean the mechanical filter for a week to jumpstart green water.

    Here's a discussion how to make the water green and vise versa.
    Apparently if u change lots of water and clean up ur bead/media frequently, water would change green rather than not change water.

    I increased my water drip 20% on top my weekly water change and clean bead daily to have better water clarity. My pond water end up green :-p
    Now reduce water drip and clean bead every 3 days once. Water slowly changing back :)

    Bro TK, Penang water is the myth then. :-)) Comes with algae.

    Bro Andrew, yes it was me at bro pandai's.

    Bro TK,

    That article is misleading because first it involves a bead filter as both acting as a mechanical n biofilter. Cleaning it daily removes the bacteria thereby enough nutrients feeds the algae instead of the heterotrophic or anaerobic bacteria that colonizes the filter media. Also not flushing often creates a dam effect and filters finer fines. IT also does not mention about the nutrient in the source water(ph, carbonate, nitrate, phosphate, etc.) that can feed the algae.

    Pond green water and mud pond green water is different. The nutrient will never be the same.

    House pond normally is kept crystal clear so that we can enjoy viewing our kois and easier to spot any infection on our koi. But the choice is still up to individual. Some with high spec show koi will not mind having green water and get whatever benefits that available. Like bro Idris for example :-D :-))

    The idea came when few people who went to breeders place saw they preparing their show kois in green water..and its a concrete pond..IMHO of cause its different comparing house pond green water n mud pond green water...but perhaps if its close too..then no harm to try I guest..

    Does green water really good for the kois? Previously I've accidentally made this happen with my pond, turned off the UV and applied kenkona koi to the pond. The second day the pond turned cloudy and slightly greenish, by the 4th day the whole pond turn green, and I could only see the koi when they surfaced to eat the floating pellets.
    I panicked and tried a lot of things, thought that I could make it clear like before just by turning on the UV, unfortunately it's not working.

    In the end, after a lot of testing, I found out the UV is the culprit, unfortunately the UV is not working. Found it out when out of desperation I added 2 more UV (previously I had 2 in the filter chamber), and slowly but sure the water turn to clear like before. Took out the 2 broken UV and it stay clear until now.

    But does green water really good for the kois? It does however caused a problem with the visibility of the pond.

    The clarity is out of the question here..if we looking in to clarity then green water is not an option...im not thinking to the display pond but at the quarantine pond..mybe keep the koi 1 or two month there...

    Captain...yes will try it at the small pond...

    In most pond and water management literature , green water is a problem not benefit. This cos the underlying causes of green water mainly over exposure to sunlight and excessive nutrients in water like nitrate , phosphates are not exactly good for kois/ fish. But sometimes even when all these causes are not present water still turns green. And maybe this could be beneficial if the correct algae is present , also minerals in water . It would help the shy kois to be more daring in this darker environment. i can see the reason for better kois emerging from these ponds but i also can see more disadvantage like not able to see / enjoy the kois and more importantly spot any issues like sinking and ulcers .

    Oxygen depletion is another problem. Need to aerate more especially at night when the algae consume more oxygen.

    Oxygen concentrator..solve the problem...

    In addition to switching off the UV, try reducing the flow-rate and turnover. Algae feeds on ammonia and nitrate. So if the biological filtration is less efficient in removing ammonia and nitrate, algae will gradually take over and do the job. Better to reduce the flow-rate in progression of course.

    If you really have a hard time turning water green, take out the filter completely, especially the bio rings, etc. Your water will turn green within a week.
  • idrisidris January 2014

    No bio rings in filter....sieve, jap mat and oyster shell only..

    Try give it more sunlight and cut down on water change and reduce water flowthro filter.
    More inportantly , also seed the water with water from already green watered pond.

    It will get green soon enough. Reversing or getting the light green you wanted is more difficult, so careful what you wish for >:-) >:-)

    Ok bro lauts tq for the advice...

    Bro Idris, pls be careful if your filter is prone to choking... the last time I had green water, quite a lot of algae came off the walls and choked up my filter mats. I think the green water competes for same food as the string and carpet algae. Just my 2 cents.
  • ray2kray2k January 2014

    Bro Idris, then wash out the filter material with tap water. Your filter really good, that's why no green water. I had my pond uv off for several months and water stayed clear until I washed out the bio rings. It then turned green real quick.

    So, basically need to upset the filter equilibrium.

    From my personal experience, taking out mechanical filter completely and completely use bakki shower for filtration will turn water green. Of course Momotaro BH is out of question, instead use only bio balls. May not be so effective as Momotaro BH, but bakki shower with bio balls will do the filtration job and leave the water green. If you want clarity back, switch back to conventional filtration system.

    Uncles, I am currently trying to "brew" some algae in a 10 gallon container under strong sunlight using water from the pond to seed some algae to maybe try it in the pond. I also sprinkled some clay into the brew and threw in some fish food too to help the process.

    You can use Green powder dye to color your water green but never try to get green algae cells in water to make it green because it cause oxygen depletion that is harmful for fish.

    i believe with sufficient blower and oxy concentrator it will be fine..hopefully

    I knew a hobbyist beforr who turned his water green very week with a little addition of malachite green dye. Within 3 yrs all his koi expired according to him. Haha..

    On a serious note, i dont think real green water is bad. The problem if the water is green because of too much pollution in the water then its bad.

    Until now im still thinking how to make my pond water green temporarily since i dont use any UV. Filter media is very clean as i dump whole mechanical and biological everyday.

    have been surprised that my pond water didnt turn green when my UV light bailed out.i was about to get another UV but saw my pond still as clear.usualy,3 days w/o UV,water turns murky,then green on the 4th day. Maybe the filter maturity helps in keeping the water clear.my pond is half exposed.but gets full sun 4 hours in the afternoon.matured filter and media does help arrest green water and algae,and frees up extra watts for another airpump!
