Fill a suitable bowl with enough water to cover the fish. Add measured dosage of Koi Sedate, and aerate with an air stone. Place fish in bowl until it rolls onto its side (normally 2-3 minutes). Lift fish, if there is any tail movement then place back into solution for a further 30 seconds and till the koi is fully sedated.
For euthanasia add two times the recommended dose. Do NOT use with salt. Do not use below 15°C.
