Seasonal Maintenance

Pond 101

We offer several different types of filtration.

Which season would you like to learn more about?


At a water temperature of 40°F, test water for high ammonia and nitrites. If you notice higher levels, perform a 25%-50% water change to help correct it. When re-filling the pond with tap water, consider using a Chlorine Remover to remove any harsh chemicals. Begin adding other necessary water treatments, like Barley Pond Clarifier. Place the pump back in your pond; run for a few hours while checking on performance, ensuring there are no leaks. 

At a water temperature of 50°F, begin feeding fish a low protein food. At a water temperature of 60°F: begin feeding fish regular food and add tropical plants. If necessary, perform a 50% water change. Always use Chlorine Remover when introducing tap water to your pond.

At a water temperature of 72°F, begin fertilizing plants. If using an Aerator during the winter, leave it in the pond to continue oxygenating the water all season. Inspect and re-establish plants. Plants that have been sitting on the pond floor can now be cleaned up and placed accordingly throughout the pond. 


At a water temperature of 85°F, Feed your fish sparingly to control the production of waste. 

Any time you clean your pond, disturb the filter, or clean a filter pad, give it a shot of Barley Pond Clarifier or Sludge Remover to jump start the growth of beneficial bacteria.

Keep the water moving with an aerator, a nozzle kit, or a waterfall. 


At a water temperature of 72°F, clear out as much debris as possible, divide and repot plants.

Replace 50% of the water in your pond and use a Chlorine Remover to remove harmful toxins from the tap water.

At a water temperature of 60°F, dispose of or bring in tropical plants, install pond netting, and start feeding fish food a lower protein diet. 


At a water temperature of 50°F, stop feeding your fish. Also, trim and move hardy lilies to deeper water.

At a water temperature of 40°F or below, remove your pump and install an aerator and/or deicer. Leaving the pump running when water is below 40°F will lower deep-water temperatures, causing potentially fatal stress to fish.

When temperatures have begun to cool, be sure to add Pond Cleaner Tablets to your pond for additional beneficial bacteria.

Drain, remove and store anything that has glass or plastic inside, such as your ultraviolet clarifier, pressurized filter and all-in-one filter. Keep them in a bucket of water in your garage, basement or other indoor area that won’t allow the water to freeze.
