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.
