Protect Your Koi From Fungal Disease

There are several water bound organisms inside our koi ponds that reside in best tranquility with our koi.

Also the microorganisms which might be nuisance for your ornamental fish require suitable water environments prior to experiencing an assault, for example the numbers of parasitic organisms living, quality of the water within the garden pond, temperature as well as the overall well being of one’s fish.

We identify such organisms as ‘opportunistic parasites’ it waits inside the guise of a buddy up to the point where the koi is vulnerable then it simply mounts an attack with achievable extreme consequences for the fish.

Fungal illness can impact almost all living things; they’re multi-cellular organisms and are present in all ponds for koi or other ornamental fish regardless of filtration methods. By closely searching at fungus in your koi we need to understand that we are operating with an opportunistic secondary infection.

Most likely an entry portal has long been produced within the koi mucus just before the fungus has contaminated, the first factor you’ll need to discover out is determine what has taken concerning the portal. The fungus attacks the wound and takes advantage of the koi mucus as a way to obtain nutrition and duplication. Probably the most widespread fungus that any of us may come across within our koi ponds is referred to as saprolegnia, typically affecting on the koi gills and whole body.

Looking similar to a yellow cotton wool impact, Saprolegnia is produced by matter, which all ponds have inside the water, which then becomes trapped onto the fungus. Fungus can develop surprisingly rapidly so it really is important which you remedy the harmed fish rapidly.

We need to initial discover the trigger of the fungus, something has clearly punctured the koi mucus that has allowed the fungus to acquire entry, and typically this is much more frequently than not a parasite. In the event you observe fungus on just 1 koi and also the other fish appear pleased and unaffected then it’s feasible that the koi has injured itself on a thing sharp within the pond and isolated therapy will suffice. Poor water high quality can hinder the efficiency of the koi’s protective layer creating the koi much more vulnerable to fungal infection.

Koi Pond - Great Tips On How To Maintain It Well

Whether it is period to switch the water in almost any place that there is fish within it just isn’t a perfect idea to change the entire thing. Any kind of abrupt environment alterations are certainly not a pleasant factor by fish in any way. Adjust on hot and cold temperature, pH, as well as chemistry within the water. In case you have an excellent filtration system it must use a biological filter as well as a mechanical filter. This is simply similar to Koi fish ponds based in the wild. The filter which gets rid of the fish waste materials that’s wiped out is the biological filter. The filter converts the waste materials into nitrite after which it transforms the nitrite into nitrate. This is certainly all completed inside the filter system. Nitrate is a chemical substance which is undamaging for the fish however it will be able to create something inside your pond that could harm your fish.

There are a few water plants that you may order which may help take away the nitrates. It will require plenty of plants remove any amount of nitrates in which you’d probably require them to. Why not consider a trickle tower to get rid of the nitrates in your koi fish pond?? Nonetheless, they are not low-priced and providing the water a partial change would certainly be far more inexpensive. Which is like water found in nature. You need to do a water change frequently however it only requires to be about 10% maybe just about every couple weeks. When it is time to change the water you will need to also see at the nitrate level by undertaking this it will help stop and discoloration in the koi pond. You can examine for nitrate using a test kit that will let you determine the nitrate level, pH, nitrite, and oxygen level in your koi pond. Identical to Koi ponds naturally taking place in the wild.

If you are planning to use tap water to change any water in your koi pond it is a great idea to make use of additives to eliminate the chlorine that is applied to the water. Chlorine will come out of the water if it sits for a few hours also.

Problem with Your Koi

Here’s a problem that one of the readers of my e-book, “What Your Pet Shop Owner Won’t Tell You About Keeping Koi” encountered (sent

via email):

“Chris,

I have recently tried to rear 6 - 8 week old koi fry in a nursery pond which is set in the wooden decking surrounding my house and they have all died in the space of one month. The fish show no signs of tissue damage, they simply stopped eating. I can’t get to the bottom of the disaster but I was wondering if it was possible that the decking, which overhangs the pond, could have leached out some toxic preservative?

Have you ever come across this happening?”

Here’s my answer to him:

“If your koi pond is new, it is unseasoned and a new pond needs to be seasoned (or ‘cured’) before introducing the fish.  And if there are too many Koi, the ammonia and nitrite build up very quickly.  One of the results of a build up of these excessive toxins is the fish not eating.

So if I were you, I would

1.  check all the parameters of the water using a test kit (level of ammonia, nitrite, nitrate, chlorine, chloramine, aeration, temperature etc).  If your tank is new there usually is not enough colonies of bacteria to get rid of the ammonia and nitrite (as you probably know, ammonia is a by-product of fish waste/urine and leftover food).  It takes about 4-6 weeks for the bacteria to grow to sufficient numbers to control the levels of ammonia and nitrites.

The ammonia that is produced is changed by different types of bacteria into nitrites and then into nitrates.  This cycle lasts until the amount of bacteria reaches a level that can sufficiently eliminate ammonia that is produced.  You should constantly (I recommend daily) check the levels of ammonia and nitrite in the water.  If the levels of either ammonia or nitrite show a positive reading, the pond is still cycling.  A seasoned pond should show zero levels of ammonia and nitrite.

2.  If you had lost your entire collection and are starting again, scrub and clean your pond and fill it anew with fresh water.  To avoid a repeat of what happened, you can try the Fishless Cycling method.  This is where you generate the cycling process in a pond without any koi.  In this method, you introduce pure ammonia into your water in a controlled manner to spur the growth of bacteria.  The aim is to replicate the production of ammonia as though you had koi in the pond, thereby causing the growth of bacteria colonies.  You can read more about how to do this in Curing a New Koi Pond.

Only when the bacteria levels have grown to sufficiently eliminate the ammonia and nitrite, do you introduce koi into the pond, but do so very slowly (one koi per week).

A New Koi Pond...cure it

3.  If you still have some koi left, make sure they are not overcrowded so as to prevent a build up of too much ammonia too quickly.  If overcrowded, you should give some away.  Assuming they are not overcrowded, check the levels of all those substances I mentioned (especially ammonia and nitrite).  If you get a positive reading, the thing to do is to make a major water change then place some fresh activated carbon in your filter.

Then you need to help the remaining koi through the cycling process.  Do so by making frequent partial water changes.  This prevents excessive build up of ammonia and nitrite.  As you change water, constantly evaluate the ammonia and nitrite levels using test kits.  You need to change water frequently (everyday if necessary).  One thing you can do during this process is to buy material that breeds the bacteria from the pet shop, like some filter media from an already established tank.  Adding this into the water speeds up the growth of bacteria.  Remember to get rid of the chlorine and chloramine from the tap water you use when you change water.  Use a dechlorinator or another type of water conditioner.

So the frequent water changes and activated carbon is to effectively reduce the levels of ammonia and nitrite which are toxic to your koi.

4.  If you have already done the above and the levels of ammonia, nitrite, chlorine, chloramine and any other toxins are zero, then the problem may be some toxins leached from your wood decking.  The wood may be treated with preservatives to make it last longer, prevent termite infestations etc.

Yes, these chemicals may leach into your water somehow.  If so, then I would add activated carbon into my filter to try to absorb it.

Personally, I think it’s more likely a build up of excessive toxins in the water that killed your koi”.
