Making tank water safe to drink is now a simple and easy for everyone to carry out. Water tanks on your house, water tanks under your caravan, in your boat, in the motor home, in the camper trailer or just on the 4 wheel drive can now have safe clean water. An Australian Made product "HydroSil" and "TankSafe" are the perfect starting point for clean water, add a filter or two and what you will end up with is clean bacteria free and dirt free drinking water without taste or odour and without using any chlorine.
