Fish Disease Diagnosis: Anti-bacterial, gram negative bacteria. Used when fish die for no apparent reason, when other medications are not helpful. Works well for Koi affected by Aeromonas (hole in the side) when mixed in feed.
Fish Disease Treatment: 1/4 teaspoonful per 30 gallons, every 3 days with a complete water change before each treatment. Or, 2 teaspoons per pound for Koi food. Feed for 14 - 21 days.
To make 1 lb of medicated food:
Put 1 lb of Koi food in a bowl
Dissolve 10 grams (2 teaspoons) of Oxolinic acid powder in ½ cup of warm water, and then add up to ½ cup more a bit at a time to create a slurry that is not too watery nor too pasty.
Pour the Oxolinic acid solution over the food in the bowl and mix well to coat.
Lay the food out on newspaper in a cool, dry place to dry or on a cookie sheet in an extremely low heat oven to dry. The food must be completely dry before packaging in a resealable plastic bag.
Store in a cool dry place or the refrigerator. The food will last about 2 weeks. Do not feed moldy food to your fish.
Feed a minimum of 10 days. Continue the treatment even if the fish improves for the total 10-day course. Treating for 14-21 days is even better.
**You will need .15 lbs of food for each pound of fish for the entire 10-day course.
Use .15 lbs of food per lb of fish
Use .21 lbs of food per lb of fish
Use .32 lbs of food per lb of fish
A large water change must be done after 3 days of treatment if used in water.
Regular observation of your fish will allow problems to be detected early. Be familiar with your fish's normal shape, size and color as well as swimming habits.
A change in these factors may signal a problem. The problem must be identified in order to know the steps to take for treatment. Every pond owner with fish, at some time or another, will probably have to medicate their pond.
Though Koi and Goldfish are extremely hardy, it is very important to keep a watch on their environment to keep them at their healthiest.
Attention should be paid to the quality of water and balance of the pond (i.e. pH levels etc.). However, if problems do occur, the first step is to remove the individual fish or decide whether to treat the entire pond.
It is sometimes difficult to be aware of a problem with a fish until its too late. Be aware of your fish's behavior patterns so changes can be detected early. A change in your fish's behavior is usually the first sign that that your fish are stressed or ill.
It is important that you know your pond's volume. All treatments are based on the number of gallons in the pond. The wrong dosage could result in killing your fish.
