Have to repeat every so often but works.
Excellent product. Says what it does on the tub
I have used the Blanket Answer in my pool and find it has really reduced the weed. I think it will need a second application to clear the rest. The pool looks much better.
this is the best product I have found to eliminate blanket weed and is keenest priced with this company
Does just what it says on the label. No problems and it cleard the blaket weed in about 5 days.
