Does a good job
I’ve ordered these for years and they always clear the algae quick in my koi pond.

Works Extremely Well. More Than Satisfied. Great Price
Worked Extremely Well. Used 2 of the 4 blocks to start. Took about 10 day to really see any results and then added the other 2 blocks and water seem to get clearer as time went by. Still had some algae lingering but I don't have a very big filter. Can actually see my fish now....and some of the bottom. Signed up for a monthly subscription. Again EXTREMELY SATISFIED with this product. VERY REASONABLY PRICE and EASY TO USE.

They work
Have bought multiple times. These work well for me to help keep my pond clear. And keeps the Agle blooms down. Helps clean the algebra off the liner as well

Did not seem to work for me
I used these in a fountain. I could not tell any difference after these were added.

It works!
Have been looking for an effective algae control product for our pond but none worked. Thought to try after reading reviews as we have a lot of sun. We have to use 2 blocks instead of one to better control the algae. Will definitely buy more.
