How do you figure application rate of Cutrine Plus Algaecide for small Koi ponds?

I have 2 ponds. One is about 20 foot long 3 foot wide stream only 1.5 foot deep. Another 20 x 15 only 2 foot deep. How much product to treat both at one application?


You should not use Cutrine Plus Aglaecide for small ponds containing koi fish.  This is the verbiage from the product label:  This product may be toxic to trout and other species of fish. Fish toxicity is dependent upon the hardness of water. Do not use in water containing trout if the carbonate hardness of water does not exceed 50 ppm. Do not use in waters containing Koi and hybrid goldfish. Not intended for use in small volume, garden pond systems.

Unfortunately we do not carry an algaecide to be used in small koi ponds.  We recommend you talk to a local koi pond supplier.
