Blanket Answer is safe for all fish, ultra-violets filters and pumps must not be switched off. Extra care should be taken if river type fish are present such as Orfe-Rudd-Roach-Sturgeon – it is important to maintain a high level of saturated oxygen if present. Decaying matter can reduce oxygen levels and lead to a rise in Ammonia and Nitrite which can be harmful to the pond environment.

When Blanket Answer is added the pond water is safe for all healthy animals and birds to drink from. For best results Blanket Answer should be used in a constant water temperatures of 10 Deg C and above, Blanket Answer can be used at lower temperatures but results will vary and cannot be guaranteed, also working timescales will be extended.

The pond water will take on a milky appearance after application this may last 4-7 days depending on the pond conditions. Over the next 7-10days the blanket weed will normally disappear in some cases it may take a little longer. It may also sometimes be necessary to add a top up dose to some ponds to finally remove all the blanket weed although adding an additional top up will not cause any harm we suggest leave at least 14 days from date of first treatment to allow time for the initial dose to complete the task.

In the bulk of cases one treatment may be sufficient but in stubborn cases we recommend regular use of Cloverleaf Prevent which has been designed specifically to keep blanket weed at bay after the initial treatment of Cloverleaf Blanket Answer.

Once the blanket weed has broken down and disappeared this will help to maintain a healthy balance in the pond by adding a unique culture of live bacteria to combat water pollution from decaying matter, this product is safe for all fish and the water is safe for all animals and birds and can be used all year round to help maintain a healthy biological balance.

Add Blanket Answer to a watering can of pond water sufficient to evenly spread the required dose around the pond to be treated.

One scoop will be sufficient for 400Litres (90 Gallons) of pond water. (A scoop is not included in the 200g tub the weight method below should be used)

It is recommended to use a set of kitchen scales and to use 10grams of Blanket Answer to 125 Litres (28 Gallons) of pond water to obtain a more accurate treatment.

Blanket Answer is only effective against “Blanket Weed” it will not clear green water or duck weed or harm plants.
