Vu-Flow CG150 1-1/2 inch Cover Guard
Sock-style sun shield for Vu-Flow filters, designed to inhibit the growth of algae and organic life within the filter body.
Simply slide the sun shield over the filter body and you are set! By blocking the sunlight that algae thrives on for growth,
your filter will not become a breeding ground for algae. Sun shields can be used in any scenario but are highly recommended
for installation where the Vu-Flow filter will be exposed to direct sunlight for any amount of time during the day.
