Floating Cover For Storage Tank - 21ft (6.40m)

An economical method of protecting water from UV rays that create the build-up of algae. By eliminating light in the water, we can drastically reduce the build-up of algae. 

Also allows rain/roof water in (as does the net cover). 

The circular shape allows it to travel up and down the tank with the level of the water.

Its construction is a specially developed UV stabilised black polythene, which incorporates bubbles to a height of 4.9mm and a diameter of 12.7mm making the cover buoyant.
