Growth inhibitor Options

[The Matrix]

When you say pond, how big you are referring to? I have seen it when I was small when my brother brought me to a fish farm somewhere in KL. Have no clue the location, probably by now it is where the Petronas Twin Tower is. Saw many oranda in a very big shallow pond. Maybe half basket ball sized sheltered pond. Is that considered big?

Well, the largest pond that I ever seen in picture on how chinese keep their fishes is several ponds of size 4x a football field. Some farms stretch thousands feet squares. Some combine farms as large as Ang Mo Kio.

If not how they ship millions of fish a month ?

Guys,
actually i was reffering to fish pond that people usually have at home. not the fish farm. those fish pond at home that just for decoration and LANDSCAPING purposes, u know what i am reffering to? well, with that kind of pond, we cant change water every week. can we?

you mean this kind of pond?

This is my 20 ton pond in which 12 tons are free swimming space and 8 tons are my filter.I cannot afford to change 100% of the water as such water maintainence include daily backflush of filters,Water top up to make up for shortfalls,monthly KMno4 treatment to ensure parasite population are under control.Monthly addition of Microlift to remove sludge and seeding of benificial bacteria.Mineral replenishment through adding of calcium bentonite clay.


Now the fish swim in crystal clear and highly polished water(paradise?)

I have scrutinised the attached pics and very surprised to realise........NO KOHAKUS!! (those not into Koi,its refering to red/white)
Anyway,I have a burning question related to this topic which I intend to ask Max (of Max Koi farm) but since you are available hopefully you can clarify:

How do koi keepers deal with nitrates and growth inhibitors?Ponds can range from 10 to 1000 tonnes of water,obviously no massive water changes done weekly.I had no chance to test the water for nitrates but would speculate that the level should be in the hundreds.Most ponds are bio-green so called,with algae on the sides and floor of the pond,looks green from above but crystal clear when scooped up. I bet your water is crystal clear though it looks green fron the pic.
My suspicion is that the amount of algae present is hardly enough to control the nitrate levels to below 50ppm,the value we try so hard to maintain for our goldfishes.
So,are kois more tolerant to nitrates and growth inhibitors?I have a friend who keeps 8 kois in 15 tonnes of water,his filtration system is another 10 tonnes by my estimation,he does water changes something like once every 4 to 6 months.Yet the kois(may I add expensive kois) keep growing.

Hi CP


Now to answer your question of nitrate management,this can be reduced in two ways
1)regular water changes
2)incorporating the vegetable filter:Notice in my attached pictures are two hydropnic plants which are feeding constantly through the water course(at the final filter)They are of Scindapsus aureus(money plant)and Monstera deliciosa(swiss cheese plant)species and are strategically planted as a landscape inclusion as well as a nitrate controller.See attached and compare the growth of these plants under such nutrient riched pond .In a way koi are more hardy and can tolerate higher nitrate but we still try to reduce growth inhibitors through religious water changes and Kmno4 bombing.
Your friend is well informed enough to incorporate a good filter to pond ratio hence the reduce frequency in water changes and another factor could be he has his hands on very good bloodline koi of reputable lineage that have parents that boast of certain length,body conformation and pattern hence the remarkable growth rate .Hope these answer your relevant question



Now can you see my Kohaku swimming on top of the pic attached(He has being with me for 6 years and is about 75cm. Its of Sakai bloodline.
Sorry for posting in this goldfish forum about koi. Moderators pls excuse me

Thanks,Goldrush.
I guess different people have different methods of maintaning water quality,or have different views and theories in the first place.My friend would have never heard of KMnO4,and I hardly see any plants at Koi farms,including their rental ponds.
Just one last question,if you dont mind.
What nitrate levels,in your viewpoint is the maximum allowed for goldfish or koi?

hmmmm .... just 1 simple question

How do you administrate KMnO4 ?

Hi matrix

I have previously posted in KMno4 discussion and explained clearly the dosage .Now to help you understand I include her a step by step pics for your referance.

First measure out the volume of water

In my case is 12 tons of water excluding the bypass filter

So for my case I can use up to 4 level teaspoon of KMno4 at 2ppm(Ucan safely use between 2-4ppm no problem)

[goldrush]

Dissove these crystals in a pail and sprinkle all over the pond surface.Make sure excellent aeration is incoporated


You get initially a dark purple coloration on administration



Check after total adminstration you should achieve a light pink coloration by sccoping out a portion against a white background tub or container(sorri I use a grey background.....experience already lah)

[goldrush]

Now dependent on your organic component of your system,the time taken for it to achieve total oxidation of KMno4 varies.If the load is heavy You may achieve brown discoloration within 1/2 hour.Now once spent KMno4 is no longer active,The second dosage of KMno4 can be administered.This time it definitely will take longer to achieve the brown discoloration.Ideally this pink hue should stay up to 4-6 hrs for max effect ie usually up to 3 bombing .A word of caution.That depends on your fishes wheteher they show any stress or discomfort.If not you can reverse the procedure with Na2HSO3 if KMno4 is still active and repeat bombing after another week.

[goldrush]

Once you are satisfied and completed the procedure proceed to reverse the discloration by adding H2o2

[goldrush]

Your fish will be swimming in better water condition with less organic deposits and surely exhibit better lustre,color appetite and finally growth................hehehehhehe

Hi cpiw 2002

I’m not too sure at which level (ppm)that nitrates will cause some distress.Signs of high nitrate level are suspected in fish showing lethargy,congestion of fins and red mouth lesion.As nitrate formation is the last component obtained in the nitrogen cycle,it is eliminated naturally through algae and plant as food.So if those bros who swear by green water,nitrates are blessings while those who swear by crystal clear water management.nitrates are curses.For goldfish enthusiasts,a great nitrate reducer will be growing water hyacinths(for breeding,providing shades as well)
For koi ponds,some of the dealers(Nippon)incorporate vegetable filters in the form of pandan leaves cultivation.In addition cpiw 2002 ,I notice your friend’s koi to pond ratio(apart from pond:filter ratio) is remarkable,hence an additional plus point why he need not water change too often or resort to any chemical intervention.
