Stopped the leak without interfering with wildlife

Our dam had been draining out into an adjacent ravine very rapidly, emptying completely between rains at an an accelerating rate. We have eels that live in the dam and burrow into the mud to wait out the dry periods, so we wanted to seal the dam wall without entombing them underground. We waited until we had a couple of days of rain, applied the product and within a day the dam had stopped leaking completely. Our eels have been accounted for and the blue yabbies seem to have either emerged from the mud or moved in from elsewhere very quickly. Frogs had spawned during the rain before the application and were completely unaffected by the product, the dam is now swarming with tadpoles. Product seemed expensive, but did exactly what we needed it to - sealed our dam without harming the wildlife.

Fantastic

For a number of years we had a slow & steady leak in a dam wall. Finally I found Dam Stop Leak. The leak was gone after the first application. The product was easy to use and arrived soon after order. Highly recommended

Dam Stop Leak® Professional - 5kg (treats up to 83m²)

This product works well. My small dam started leaking very badly. You could almost watch the water running away. The granules were easy to spread and stopped the water loss almost immediately. The order was delivered as quickly as could be expected (within five working days) and there was no problem with the shipping. I happily recommend Stop Leak as a product and Aquatic Technologies as a supplier.

Great purchasing and delivery experience, time will tell if the product works!

First time, and hopefully last time in the near future, have used the Dam Stop Leak product, being a relatively small dam we managed to spread the granules by hand and worked reasonably well. Time will tell if it managed to stop leakage.

Pond seal

My dam was losing on average 150mm per day to a level that it would settle at, now the water has stopped dropping so I’m really impressed with the results from a very easy product to apply. Thanks

Leak stopped

The product was straight forward to use and has stopped the leak. I would highly recommend it. I have a small dam large pond approx 75,000 litres. Watched the leak diminish over 2-3 days and then stop completely.

Coptrol treatment will vary depending on the severity of your algae bloom. For severe algae blooms use the lower volume or surface area to calculate how much Coptrol needed.

Coptrol™

For the safe control of all types of algae in all types of water bodies.
coptrol-15l-and-1l-png

How it works

Algae actively seek out and absorb Coptrol for its nutritional value. Once absorbed through their cell wall digestive enzymes within the algae cell breaks down the copper chelate and releases the active constituent inside the algae cell to kill it. Coptrol is solely used for the control of algae and does not control aquatic plants.

Method of application

Once diluted, Coptrol can be applied directly from a bucket, watering can, knapsack sprayer, horticulture sprayer, firefighter pump sprayed from the bank, or from boats or aircrafts.

Alternatively Coptrol can be dripped directly into flowing water in high volume treatments such as flood irrigation water.
