Medications for Use in Ponds

Salt is the original treatment our ponds, used back in the 1900's and before

1) Salt that is safe for use in treating fish, should contain as few additives as possible. Pure vacuum dried salt, medicated fish salt or plain old cooking salt are acceptable for use.
However table salt contains too many additives for use in the pond or QT.

The use of salt in the quarantine tank, eases the load on the kidney of the fish, which is important when your koi or goldfish has dropsy and or problems with buoyancy

Salt may also be used in a short term salt bath good for ridding the fish of any parasites prior to going in your pond.

Do not use salt with Anesthetic, Formalin,, zeolite or Roccal as you will find that it reduces the effectiveness. Use only the dosage suggested for at 1/2oz per gallon imperial/or US equivalen.

2) Malachite green has a use as a bactericide or fungicide, but it can also be effective against some body parasites.

We normally use Malachite in conjunction with formalin which is used to kill parasites, it does so by removing the mucous layer on your fish as most adult parasites burrow below the mucus layer.

Every time you remove the mucous layer during treatment of fish, remember that fish are prone to the risks of bacteria and fungal infection.
Why? Because the mucous layer is part of the fishes defense system.

Malachite may also be used along with propolis to paint any wounds by parasites and fungal infections. Propolis is a by product of bees, it has since found its way into treating fish wounds.

"Propolis is a resinous mixture that honey bees collect from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the hive. :"

3) Formalin It removes the mucous layer that harbors the parasites, malachite green is traditionally used in conjunction with formalin .

It is a very toxic substance, great care is required when using it. Do not sniff the open bottle of formalin and always wear gloves when using it also protect your eyes .
If your formalin has turned cloudy or has white crystals on the bottom then it is unsafe to use on your pond.
Do not use Formalin with a Ph of 8.5 things can turn toxic.

3) Superverm is used to eradicate Gill and Skin flukes. Dosage - one treatment of 11ml per 1000 gallons.
Do not use in a goldfish pond as Superverm is deadly to goldfis.

FlukeM by Kusuri is another good fluke medication.

4) Potassium permanganate or PP as we know it, is very effective as a pond bactericide can be used as a equipment disinfectant.

Low water temperatures make treatments less effective and sometimes dangerous for the fish.
PP however can be used at all water temperatures.
It will not only lower bacteria but will also help to eradicate protozoan infections such as Trichodina..
Make sure that the crystals are completely dissolved in hot water before it is introduced into the pond. It is best to prepare the solution in a plastic container allow it to stand for half an hour before use.
PP should never be mixed with other chemicals. Wait at least a week if you have been using them. Make sure you do a substantial water change to be on the safe side, before using the PP.

It is not to be used in strong sunlight, hot weather.

5) Sterazin P can be effective against Gill flukes and Skin flukes. It is best used at temperatures above 15c.
Sterazin P is most effective when used with salt

Treat on days 1,3,6,8 and 10.
Sterazin P is one of the safest treatments especially for the less experienced.

6) Acriflavine is used as a bactericide. It can also be used topically to treat a wound.or as a disinfectant it can be use in conjunction with Formalin and Malachite. It can also be used in conjunction with salt as a very effective treatment for many of the minor problems our fish get in the pond
It is an ideal product for use in QT. Dosage

7) Chloramine T is used as a bactericide and to treat bacterial gill disease.
It can also be effective in the treatment of White spot Costia and Skin flukes.
However to be effective for the treatment of fluke infestations, several treatments are required at intervals that depend on the water temperature. The life cycle of these parasites is faster up as the water temperature rises.

I have not put in any dose rates for chemicals simply because of the differences between our respective measurements i;e Imperial and US gallons. When using any of these chemicals make sure you check out our respective dose rates on the bottle or container these chemicals are held in
