Parasites - Costia
Costia has various options of treatment. They are in order of the best method.
• Salt Treatment (Do Not Use Other Treatments While Salt Is Present)
For fish that have gill damage and/or difficulty breathing, salt baths are the safest option. This salt bath should last for 72 hours to be sure all costia are dead. To minimize stress to your fish, first start with a concentration of 3 grams per liter (.3%). After 12-24 hours, increase this another 3 grams up to .6%).
If your fish seem to be handling this alright and don’t appear stressed, increase again to a maximum of .9% after 48 hours. Fish should be eating normally again and shouldn’t display signs of discomfort like flashing or clamping fins. You can now slowly decrease salt levels by performing daily water changes of 25%.
Pond treatment for parasites and snails: 2-4 g / 1000 liters.
Keep on adding in small doses of 2g/1000 litre to keep the pond water pink for 1-2 hours
Pond treatment for bacteria and ulcers: 2-4 g /1000 liter
Keep on adding in small doses 2g/1000 litre to keep the pond water pink for 8-10 hours
Dip: very effective for parasites, bacteria, ulcerations etc. Use 1 gram per 10 liter water for 7 minutes. Always aerate and ALWAYS remove the fish if it gets restless and jumpy. Control timing precisely and do not treat too many fish at the same time unless you can time the treatment of each fish correctly.
This treatment tough, can push an ailing fish ‘over the edge’. Therefore fish already weakened by disease should first be treated with a 30-50% dose first time. Alternatively simply shorten you dipping to 1-2 minutes if the gills are infected and necrotic.
Important. Always de-clog the gills with a Peroxide (hydrogen peroxide) treatment to the pond. It not only terminate the action of the potassium permanganate, but will clear the water from the brown colour. Will also aid in removing the brown coloured necrotic tissue from the gills.
I want to warn about use with salt. Salt (NaCl) is additive to potassium permanganate. To strip parasites from basically HEALTHY FISH can be tolerated, but sick, weakened fish should never be subjected to such treatment and will surely die. Always test salt level or ask the pond owner about his salt regimen before deciding on the protocol for the potassium permanganate treatment.
For certain phenotypes of the Doitsu koi the uptake of oxygen is poorer for certain physiological reasons. They stress more quickly and die due to oxygen starvation. Use half the recommended dose/time when dipping the first time at least to determine their suitability for the treatment.
> Scrape the Koi first before treatment
> Identify which Parasite is causing the problem before treatment
> Make sure the pond water is salt-free because it can harm Koi when used with most chemicals
> Calculate the Volume of Water accurately
> Turn off the UV Unit when treating your Pond
> Test your Water Parameters before Treatment
> Follow the label’s instructions and do not overdose. Chemicals can cause serious damage to your Koi if amounts are miscalculated
