It works so far
Worked well on the moss and algae in my pond. I have only treated half my pond so far (per the directions). Will treat again in 14 days so hopefully that will take care of the rest of the moss and algae

Good Product, Cost Effective for Larger Bodies of Watet
Good for algae in stock tanks. Effective and versatile for both floating and submerged algae. Takes some trial and error to get the proper mixture for your individual needs. Mixing instructions are overly complex and somewhat difficult to interpret. I felt as if the instructions and mixing guides were written to protect the manufacturer from liability rather than to actually help the consumer. I use Cutrine alone or in combination with diquat depending on the problem which has arisen. Once you get your mixture right Cutrine is an effective, economical treatment. Does not kill Duckweed or Azolla.

Worked great for spring pool prep.
Filled my pool from the well this month. The water was brown. Couldn't even see the 2nd step of the pool. The 2nd day the brown became a green. Put two cups of Cutrine Plus in the deep end. Two days later it went back to brown. It took 5 days of cleaning the filter 2x a day but the pool was crystal clear day 6. No algae in the (new) filter. As ppl who do their own pools know algae in the filter drastically reduces the filter's efficiency reducing the time between necessary cleanings. Algae in the filter was my biggest concern.I let the pool go for another week with high chlorine and algaecide levels to clean the tannin stains and scum lines accumulated during the winter when it was drained. The levels of chlorine and algaecide reduced over time and filter cleanings. I declared it ready and the Ex came over and collected a bottle of pool water to have it tested. It tested 'perfect' at the local pool supply store and she was complimented on how clean the water was.IMO this is good stuff for spring pool startup. Since it's not specified for swimming pools I'm sticking with In the Swim's pool algaecide during swimming season. They're both copper-based but....

It works perfectly to kill algae
This cutrine plus is easy to use and effective. I've been using it for 20 years and it's still the same. I mix the recommended ratio of 1 gallon to 9 gallons of water. I spray this solution directly on to the algae. The algae is dead the next day and doesn't come back. More algae will appear eventually and you'll need to reapply. I spray moderately. You don't need a lot on the algae to accomplish your mission.

Good product; Amazon won't ship to house address
I've ordered this on a subscription for two years, and in the last 6 months, Amazon will no longer ship to any addresses I have setup.

Don’t waste your money unless you own a good size lake
I got this algaecide last year thinking of cost effective turn out such a waste of money. I didn’t return it after reading the label though maybe it will last for a while. For 900 gallons back yard pond like mine just need a couple of ounces will do the job even made my koi stressed for a day. I do have UV light with my filtration system so only used twice for the whole season. Spring comes I use it again wow no longer work at all ,only make my koi stressed but the surface of the pond stay green color.Do not recommend to buy this product unless you own a lake and use it all in one season.
