Using a unique two-stage process exclusive to us, this natural, microbial treatment starves algae of nutrients and digests the resulting dead organic matter, leaving your pond crystal clear. Step 1 kick start oxygenator - natural bicarbonates and related substances release oxygen, starving algae and weed. You’ll see results in just 3-4 days. Step 2 pure aqua - introduces a natural biome of bacteria to maintain pond clarity. These degrade muck and slime that has accumulated in the bottom of the pond, clarifying water and establishing long term populations. Note that to work, the microbes need the water to be 10°c or more to work - so use April to October. Some benefits of pond clear pro can be observed immediately after dosing commences, although major improvements in water clarity frequently take a few weeks to become apparent. By using kick start as a pre-treatment, you’ll see results much more quickly.
