CrystalClear KnockOut Plus is an all-natural, fish treatment that eliminates plus prevents external single-celled parasites, ich (ick), and fungal infections. KnockOut Plus works extremely well with pond fish species such as koi and goldfish and unlike most fish treatments, there is no need to remove your filters before treatment.

Standard Application Rate

Shake well before using. Upon discovery of infection, apply 1 ounce of KnockOut Plus for every 60 gallons of water daily for 7 consecutive days. When there are no visible signs of infection, it is recommended to continue treatment daily for an additional 3 days to ensure infection will not return. Disperse over the majority of the surface area of the pond.

Persistent Problem Application Rate

Shake well before using. For infections that last more than 7 days after standard application, treat twice per day. Apply once in the morning and once in the evening. Do not apply as a bath application. KnockOut Plus works best as an in-pond additive.

Preventative Application Rate

Treat daily for 7 days anytime new fish are added, during pond clean-outs, during spring start-up or any time fish are stressed.
