Expert:  Martin replied 7 years ago.
Not many product won't hurt the fish. Some non toxic floating dye allow to block enough sun to reduce all algae growth. Other liquid will be simply poisonous or cause algae to dyes too fast and will cause a big lack of oxygen in the pond because of decomposition.

The best way is to attack the problem from many angles. Try to have tree around the pond to reduce sun getting in it and to prevent nitrate all around to flow to it. Try to introduce air in the pond (wind will work great for that). Introduce vegetation eater species like grass carp. Introduce Nymphaeaceae (water lily) to prevent sun to enter the water.

As i don't know the product, i can't comment more on this. What you can do with it is test that said. You get a sample of the water, you use a certain quantity and you note the result. You can even try toxicity test with a tadpole, if the tadpole survive the concentration, a fish will survive (that said it does not mean they will feel well :)).

Usually, if it's copper based, you can be pretty sure it will be toxic. You should have a phone number on the gallon, the manufacturer can lie on the efficiency of the product but not on the toxicity.
