Safely Adding Water & Fish

Ponds may accumulate a build-up of waste that diminishes water quality and disrupts the pond's natural balance. Performing a monthly water change of 15-25% is recommended during the pond season to reduce the build-up of pollutants.

Whether changing or adding water, add API® POND STRESS COAT™ water conditioner to remove the harmful chemicals in tap water. POND STRESS COAT water conditioner is also recommended when adding fish to a pond, as it contains the healing power of Aloe Vera to repair damaged skin and adds a protective slime coat to reduce fish stress, making them less susceptible to disease.

Maintaning A Clean Pond

All garden ponds accumulate a certain amount of waste from dead plants, algae, uneaten fish food, and fish waste. As waste decays, it creates toxic water conditions, removing oxygen and lowering pH levels in the water.

Adding beneficial bacteria is an easy, natural way to keep your pond clean and healthy. POND-ZYME™ SLUDGE DESTROYER™ bacterial cleaner and POND ECOFIX™ SLUDGE DESTROYER™ bacterial cleaner contain special bacteria uniquely suited to consuming pond sludge. Regular use will help keep your water clean and clear.

POND-ZYME SLUDGE DESTROYER bacterial cleaner is a 100% all-natural product, and is safe for all pond fish, plants, and wildlife.

Monitoring Water Conditions

It is not possible to know the condition of pond water without testing it, so regular water testing is the only way to protect the health of all pond life from deteriorating water conditions.

The API® POND MASTER TEST KIT is the easy and accurate way to test pond water quality. This kit measures four main parameters in your pond water: pH, ammonia, nitrite, and phosphate, and contains test tubes, color charts, and an instructional booklet for fast and easy testing.

API POND 5-IN-1 TEST STRIPS are another fast and easy way to evaluate water conditions. Simply dip a test strip in your water and compare your color results to the chart provided. 5-IN-1 TEST STRIPS test pH, nitrite, nitrate, carbonate hardness, and general hardness in pond water, and should be used weekly to stay on top of pond water conditions.

Creating A Beautiful Water Garden

Aquatic plants will produce more blooms and achieve their greatest potential only when provided with the necessary nutrients.

Potted aquatic plants will benefit from the addition of API® AQUATIC PLANT TABLETS to the soil. When used in combination, these two fertilizers will promote the continuous formation of buds, spectacular flowers, and lush foliage on all pond plants.

API AQUATIC PLANT FOOD TABLETS contain essential nutrients and iron that feed pond plants and stimulate beautiful blooms all season long, as well as boron to promote continuous flower formation. Feed AQUATIC PLANT FOOD TABLETS once per month in the spring when water reaches 50 degrees Fahrenheit, then twice a month when water reaches 70 degrees.
