Frequently Asked Questions:

How much water does the 32 oz bottle of API Pond AlgaeFix treat?
The API Pond AlgaeFix 32 oz is a highly concentrated formula that treats up to 9,600 U.S. gallons. It is ideal for medium-sized ponds and water gardens. To ensure precise application, the standard dose is 1 teaspoon (5 ml) for every 50 gallons or 1/4 cup (60 ml) for every 600 gallons of pond water.
Is AlgaeFix safe for Koi, goldfish, and live pond plants?
Yes, API AlgaeFix is EPA-registered and safe for fish and plants when used as directed. However, because it works by rapidly killing algae, it can cause a sudden drop in dissolved oxygen levels. It is critical to have vigorous aeration running 24/7 during treatment. Note: This product is NOT safe for snails, shrimp, or crayfish.
How quickly will I see results after using AlgaeFix?
Most users see visible results within 24 to 48 hours. AlgaeFix targets the cell walls of green water (Chlorella), string algae (Spirogyra), and blanketweed (Oedogonium). For heavy blooms, repeat the dose every three days until the water clears, then switch to a weekly maintenance dose.
Can I use AlgaeFix in a pond with a UV clarifier or bio-filter?
Absolutely. AlgaeFix is compatible with both mechanical and biological filtration systems. While a UV clarifier kills suspended algae, AlgaeFix targets attached string algae that UV lights cannot reach. Combining these methods is the most effective way to maintain crystal-clear water.
Does API AlgaeFix have an expiration date?
API Pond AlgaeFix has an indefinite shelf life when stored properly in a cool, dry place. There is no expiration date on the bottle, making the 32 oz value size a great investment for multi-season algae control.
