How to Use

Step 1: Determine the size of your water feature.

The volume of water should have been provided when you bought the water feature. If you don’t have this information, the vendor you purchased it from should be able to supply it to you. If you have a pond or other large water feature with standing water, you can calculate it using the calculator below.

Step 2: Dosage of Fountain Refresh

Use the following table to determine the recommended dosage. Apply once every 2 – 3 weeks.

Water AmountDosage
1 gallon5 drops
10 gallons1/2 capful
50 gallons2 capfuls
300 gallons2 oz.
1,200 gallons8 oz.

Step 3: Adjustments

Under some circumstances you may want to adjust the dosage. However we recommend using the dosage in the above table if pets or wildlife drink from your water feature.

If your water feature is particularly dirty or overrun with algae, you may apply up to 5 times the recommend dosage. You should see results in just a few days. Once the water appears to be clear, we recommend cleaning your water feature and adding new water. Once the water is clear or new water is added. You should then return to the recommend dosage.

If you have been using Fountain Refresh for a week with little to no results, it could mean you have overly hard water. In that case you may double the dosage. If you still aren’t seeing desirable results, you may go up to 5 times the recommend dosage.
