Questions & Answers

I have a 10 gallon fountain that needs a nonclorine product to control the algae. And something that will not damage the plants below the fountain when splashed on. Will this Fountain Block be safe for the plants below the fountain?
Answer by ChewyJan 10, 2018
This product is not intended for use with live plants.

Harmful to birds?
Answer by ChewyJul 14, 2017
The Diuron is only slightly toxic to birds and Copper Sulfer Pentahydrate poses less of a threat to birds than to other animals according to studies performed by Cornell University. At the low levels used in this product that make it safe for fish (which are more sensitive to it than other animals), this product should not be harmful to birds when used as directed.

Can this be used to prevent algae in pet water fountains?
Answer by ChewyApr 13, 2018
This product is not recommended for use in drinking water.

I have a small water fountain (not part of a pond) that occasionally the dogs sneak a drink of water out of. Would I be able to use this to control the slightly cloudy water and beginning stages of green guck?
Answer by ChewyAug 15, 2018
This treatment has not been tested for safety if dogs drink the water, it would not be recommended.

good for a smaller pond

it did turn the water from algie to clearer but still cannot see the fish , perhaps like my headline,if my pond was smaller would do the job! And at least it does not harm the fish!!!

Algae Control Pond Fountain Block Water Treatment

I just started using this product, but it already is working very well. I would recommend it. The blocks are small, unlike the big round tablets that you usually would use, so it looks a lot better in the pond and does the same job.

Didn't Work

We put 2 tablets in the fountain and it didn't do anything to get rid of the algae. This was after we scrubbed the fountain down, added fresh water with the tablets and algae still grew.

Clean Fountain

We put it in our fountain and it works amazing. Our fountain would be green by the next day when it’s hot. We put the tablets in the water and it’s been green free for weeks on the middle of summer.

No more slime

After trying many different products with little noticeable difference - this works! My fountain looks beautiful all the time.

So Far So Good

So far so good my biggest concern was the birds we have lots of beautiful birds that drink out of our fountains I think it's all about the right portion of the Block in your fountain and water looks beautiful.

WORKS GREAT!

After trying several other products to prevent 'green water' in my recirculating garden fountain without success, this product solved the problem almost immediately. Sparkling clear water without a mess. Perfect!
