Took the cover off my 15 foot pool today to find the water very clear, but on the bottom of the liner in the centre was a patch of green algea growing about 6 square feet in size , so i checked the water chemicals to find chlorine was fine and the ph was a little high (pool had not been used for about 3 weeks) but i had checked the chemicals every 4 days filters had been run for 10 hours each day. i tried to use my super vac but this did not seem to work as the green stuff just seemed to blow out through the bag so i brushed the bottom of the pool but now the water is all a light green colour but it did remove the algae from the liner, i have shocked the pool with my regular chlorine granuals now at about 11.0 ppm . question... should i now use a Algaecide and how long will the green water last pool only has a skimmer that came with the splasher pool which is now running constant.
Many thanks for any help
