Hi Yinh,
I agree with our friend. You have to give more details about your pond: a) What capacity? How many kois? How big are they? What filter system do you need?
EMERGENCY MEASURES:
1) Put your sick kois in another tank before they make your other kois sick.
2) Try SALT. Salt is a first aid treatment. Use rock salt or sea salt. DO NOT USE IODIZED salt. It can kill your fish. If your quarantine tank is small. Dissolve 1 teaspoon of salt per gallon of water. If your tank is big, dissolve 1 pound of salt per 100 gals of water. Dissolve the salt in a pail before pouring it to the tank. DO NOT THROW SOLID SALT INTO THE TANK. If your kois eat them in big quantity, they will DIE.
3) Along with the salt, you can add TETRACYCLINE CAPSULE 500 mg (1 capsule per 20 gals water). Combine it with Methylene Blue (5 drops per 1 gals).
4) If there is sign of improvement, make 30 to 50 % water change and dissolve same proportion of salt and medicine that is displaced by the water change.
5) According to koi lovers, you can increase salt treatment concentration up to 3 teaspoon per gal or 3lbs per 100 gals. But I would rather play safe by doing a maximum of 2 teaspoon per gals.
5) If there is no sign of improvement after 3 days, try FURUSAN, it a yellowish JAPANSES KOI DECEASE powder. One of my koi used to have a coin-size ulcer that ate through the flesh and reached the bone. It got healed with FURUSAN but left an ugly ulcer.
TREAT YOUR ENTIRE POND:
1) It seems like your entire pond has already been infected because another koi has become sick. If you do not treat the entire pond, all others will sooner or later get sick.
2) Make a 75% water change. If your water source is from the tap, put ANTI-CHLORINE or DECHLORINATOR SOLUTION. If you do not do so, the chlorine in the water will poison your kois. Apply it according to instruction on the label. In the Philippines where I live, the dosage is 1 teaspoon per 10 gals of water.
3) Do salt treatment using the dosage mentioned. If you have plants in the pond, remove them because salt can kill your plants or make them turn yellow.
CHECK YOUR FILTER SYSTEM: Usually, the fish got sick because the water quality is bad... because your filter system is insufficient. If your filter system does not produce healthy water for your kois, you can use as much medicine as you can afford and your kois will not stop getting sick.
Healthy water makes healthy kois. Healthy kois makes happy you!
