Why Add a Pond Block Now, at the End of Winter?
As winter draws to a close, your pond’s ecosystem needs a boost to prepare for the warmer months ahead. Adding a Pond Block now is one of the best steps you can take to support water clarity and fish health—especially in ponds 2000L or larger.
What Does the Pond Block Do?
-
Treats up to 5000L per block
-
Boosts beneficial bacteria levels
-
Clears cloudy & green water
-
Breaks down ammonia, sludge, and organic waste
-
Removes heavy metals
-
Buffers pH & prevents oxygen depletion
-
Safe for fish, plants & wildlife
-
Made in Australia – 100% natural biological treatment
Why Apply It Now?
-
Winter reduces beneficial bacteria
Cold weather slows microbial activity. Replacing bacteria before temperatures rise helps prevent algae blooms and water quality issues as fish become more active.
-
Prepares your pond for spring
As water warms above 15°C, the block becomes more effective. Applying it now ensures it’s colonized and working by the time your pond “wakes up.”
-
Post-winter clean-up
Ponds accumulate sludge, organic debris, and ammonia over winter. The Pond Block helps break this down naturally before it becomes a problem in spring.
How to Use:
-
Optional: Do a 20% water change to speed up the cleaning process.
-
Place the correct number of blocks in a low water flow area (not near waterfalls or filters).
-
For heavy sludge, place the block directly into the buildup under water.
-
Leave it in place—do not handle again once submerged.
How It Works:
Beneficial bacteria and enzymes grow on the block and work continuously to consume harmful waste, nutrients, and toxins—the root causes of algae, murky water, and poor fish health.
Don’t wait for water problems to appear. Start the season strong—add your Pond Block now and enjoy clear, healthy water all spring and summer!
