The liquid ones have gone up in price but don't really control the algae that grows in my fountain. This one does the trick and is reasonably priced. We placed this in the fountain and it goes to work. No need to remember to add it quickly. We were gone on vacation and thought for sure we would need to clean the fountain upon our return, but no, the algae block did its job. Would definitely recommend if you have an algae problem. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003DASH9U | | Brand | Tetra | | Brand Name | Tetra | | Customer Reviews | 4.2 out of 5 stars 1,526 Reviews | | Global Trade Identification Number | 00046798167372 | | Item Form | Granules | | Item Weight | 0.01 Ounces | | Liquid Volume | 10 Millilitres | | Manufacturer | TetraPond | | Manufacturer Part Number | 16737 | | Model Number | 16737 | | Target Species | Homeowner | | UPC | 707005178078 046798167372 | | country-of-origin | USA | ## Product Details - **Brand:** Tetra - **Item Form:** Granules - **Item Weight:** 0.01 Ounces - **Liquid Volume:** 10 Millilitres - **Manufacturer:** TetraPond ## Images ![TetraPond Anti-Algae Blocks for Fountains, 6-Count - Image 1](https://m.media-amazon.com/images/I/81oYdPeS4LL.jpg) ![TetraPond Anti-Algae Blocks for Fountains, 6-Count - Image 2](https://m.media-amazon.com/images/I/815HxO09lBL.jpg) ![TetraPond Anti-Algae Blocks for Fountains, 6-Count - Image 3](https://m.media-amazon.com/images/I/71-y7dKLBNL.jpg) ![TetraPond Anti-Algae Blocks for Fountains, 6-Count - Image 4](https://m.media-amazon.com/images/I/51JgpeEAy8L.jpg) ![TetraPond Anti-Algae Blocks for Fountains, 6-Count - Image 5](https://m.media-amazon.com/images/I/91SHLv93I9L.jpg) ## Questions & Answers **Q: Do you have to clean out the algae before using this product?** A: Thank you for your question, Donna! We do recommend cleaning it out, if possible, as this product is more of a preventative product. It doesn't work as well at killing algae that is present as it does at preventing it from occurring. Customers rave about this product when put in prior to algae growth. So if you clean out your fountain first, then refill it and drop this in, you should not have algae the rest of the season. **Q: I have a lot of birds drinking from my fountain now, are the Flountain blocks safe for wildlife?** A: Customer feedback over the years has indicated that these are safe for birds. However, we want you to be aware that we have not tested them specifically for this purpose, and cannot guarantee the safety of the birds. They do dissolve slowly, and are very diluted in the fountain. **Q: will this item harm birds drinking from the fountain?** A: Birds did drink from fountain but have no way of knowing if it harmed them. Does say not to use with plants and may be toxic to fish. Was getting lots of green algae. Started using PHYSAN 20. Just a few drops each week. Water is so clear and haven't had any algae. Water will foam up when more water is added but doesn't last. Always have a block in the fountain as a back up **Q: Do you place the block on the fountain "floor" or do you need to place it in a floating container?** A: Thank you for your question. The Tetra Pond Fountain Block is typically placed at the bottom of a fountain reservoir where it can gradually dissolve to control algae growth. If you have additional questions you can call Pond and Garden Depot toll free at 1-866-305-5459. Sincerely, Keith H. Customer Service ## Customer Reviews ### ⭐ Not recommended *by G***N on 13 November 2020* Killed my fish ### ⭐⭐⭐⭐⭐ Algae Under Control *by D***. on 22 April 2025* I've been looking for a quality algae control for awhile. The liquid ones have gone up in price but don't really control the algae that grows in my fountain. This one does the trick and is reasonably priced. We placed this in the fountain and it goes to work. No need to remember to add it quickly.

Would definitely recommend if you have an algae problem. ### ⭐⭐⭐⭐⭐ quick and effective *by J***Y on 27 January 2024* My small waterfall/pond was getting overrun by green algae. A friend recommended this product, so bought it and once in hand, dropped a single small block into the pond near the pump inlet. Within a few days, water was clear again, and within a few weeks, all the stones were clean again. Pretty amazing. The package label is a bit confusing though, because it shows pictures of fish on it, like for use in Koi pond, but fine print says it will kill fish and birds. Not sure about the actual dangers, but the newts we have running about during rain (and getting into the pond) have not diminished in number. ## Frequently Bought Together - Tetra Pond Fountain Block 6 Count, Controls Algae Growth In Ornamental Fountains - EasyCare FounTec Algaecide and Clarifier, 8 oz.
