In hot weather, I have to go back to the first plan -- every three days. That type of use has not harmed the snails, fish, turtle, or frogs in the pond, but it does zap the algae quite well. I hope this helps. Oh, I put it in the pond in the early mornings, not when the sun is roasting. We are reaching 107 degrees here right now. I also insert the product where the stream flows into the pond so that the mix is dispersed quickly. I mix it in a small bucket of water before pouring it in the pond. **Q: Is it safe for water fowl, ex. duck, egrets?** A: It is toxic if not diluted; use as directed and mix in water in a container before adding to pond then is safe for anything! **Q: What will work in a water feature with two pumps, flow and two waterfalls. About 1000 gallons. Algae grows on the rocks.** A: The best thing I have used is algaefix. Follow the directions on the bottle. I use it about once every week to keep my 3000 gallon clean..... **Q: is this safe for birds?** A: I use this product 1x/week in summer. The fish need an extra oxygen source while this kills algae, for first 24 hrs after adding to water I make a point of keep filter on AND running fountain for O2 source. The fish all move to directly under the return line within an hour after treatment. Safe to koi, goldfish, pond turtles, the lizards and a crow.. have all survived a dip in treated water. Also, savvy pond shop guy told that once algae is under control, cut back on dosage and see how much you can decrease recommended treatment amount while still algae free, we can go from 1.75 cup to 1.15m so maintainence is @ 30% less. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Drain a bit of your pond to speed up results and you won’t regret it *by on Reviewed in the United States July 5, 2026* Works great! Fish and plants are safe, dogs drink from the pond and they are OK too ha ha 😅I had bought a lily with a little bit of string algae and within a few weeks it was spreading and the entire pond was turning green so I looked up a bunch of different solutions and this seemed to be the safest and best results. I used as directed with about a quarter cup per 600 gallons and it did ok, but there was still major algae on my beautiful rocks so I drained the pond half way, let the sun cook the algae on the dry rocks for a couple days then mixed about 1/8 of a cup of the algae fix in a spray bottle of water and coated the stones where algae was and let it sit for a hour before filling the pond back up with hose water and turning the little stream back on and WOW 🤩 I can see the detail in the stones again with ZERO scrubbing and the stones under the ones I sprayed are also starting to clean up with crystal clear water!! Will definitely use when needed for ever ### ⭐⭐⭐⭐⭐ If you have an algae problem this will solve it. *by on Reviewed in the United States July 5, 2026* This stuff is awesome! I’ve used this for years! You can see it working within 15 minutes as bubbles start to rise to the surface. In 1 day you can see a difference. If you are pitch green and can’t see anything it will take about a week and you may need to retreat. My only complaint is the price tag. I want to try another brand too because I can’t keep up with the price. Other competitive brands offer algaecides $20 less. I buy about 2-3 a year, so that’s my only complaint. ### ⭐⭐⭐⭐ So Far, So Good *by on Reviewed in the United States August 3, 2026* Seems to do a good job. Adding more frequently to the fountain, as water's evaporating so I have to keep adding water.So far, pleased with this product. ## Frequently Bought Together - API POND ALGAEFIX Algae Control 32-Ounce Bottle, FISHAQUARI (169G) - API POND ACCU-CLEAR Pond Water Clarifier 32-Ounce Bottle - API POND-ZYME SLUDGE DESTROYER Pond Cleaner With Natural Pond Bacteria And Barley, 1-Pound Container --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/775725766-pond-algaefix-32-fl-oz-pond-algae-control-copper-free](https://www.desertcart.sg/products/775725766-pond-algaefix-32-fl-oz-pond-algae-control-copper-free) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-20*
