I think it reduces my need to use chemicals in my pond to control algae.

Excellent at controlling the algae, just change each month. The container is under water so you don't see it.

It works. Makes our pond clear. Works better than barley. Easy.

This a wonderful product. Handles algae growth, but leaves some for the fish to eat. It goes in a small black container that you just twist off to refill. very easy to use and fast installation.

Good for clearing the water. Have been using a similar brand from [...] These are the same product (different manufacturer) and a lot cheaper

Comments about Submersible Refills, Set of 4:

My rain barrels develop a strong odor and the water turns bad after several weeks sitting in the 100+ heat. After talking to the people at Gardners.com, they recommended that I try this product, but cut each packet into quarters (a more appropriate size for my 75-gal. barrels). I did that and put the packets in the already bad water, but it did nothing to clear it up. After some recent rains, the water did smell better, but I am guessing it is because most of the bad water was forced out by the new rain water. I am not pleased with this product, but I can't say it won't work if you put it in when your water is still good.

I have used this for years in my 300 gallon pond and wouldn`t be without it.

I have been buying this for several years now - it keeps my water crystal clear but I still need something else for algae.

I have been using this product for 4 years. My first pond was 650 Gallons and had no fish and it worked great. My new pond is about 500 Gallons with about 20 fish and it works great in it too. I just have to replace the packs more often. It cleans with no chemicals which is great for my fish.
