Filter Care
The Davey Media Filter is the heart of the pool equipment installation. Proper care
and maintenance will add many years of service and enjoyment to your pool. Keep
the exterior of the filter clean, using a mild detergent and water.
Water Quality
Maintaining balanced water chemistry is important to the life of your pool equipment.
This filter is designed to be used with Pool & Spa water, balanced in accordance
with Langlier Saturation Index, with a pH level of between 7.2 and 7.6 and is
regularly treated with a chlorine sanitising agent with the level not exceeding 3PPM.
Please consult your local pool shop regularly to have your water tested.
