How bad would it be to just throw the winter cover over our pool full of green water, and deal with cleaning it up come spring time? We are new pool owners, and even though the water was crystal clear all summer, failure to maintain has allowed it to become a green swamp. We have vacuumed and scrubbed the liner as well as possible (since we can't see the bottom), and believe we have removed most of the leaves, based on the filter basket. We've already dumped about 6 gallons bleach in over the past couple days, nothing seems to be changing. Its now cold and rainy and I'm frustrated!
