I opened my pool this year to a brown swamp with thick green algae on every surface. After tons of money and filtering and backwashing, the pool was a sparkling clear blue. We used: 2lbs green to clean, 19lbs of shock, and superfloc to get it clean. (13,000 gallon pool).
After putting our solar cover on the pool for 3 days, suddenly the water turned green and cloudy. I put a quart of Leslie's Algaecide (60% Polyquat) and about 4lbs of shock and nothing happened. Yesterday I replaced the extremely old sand with Zeosand and ran the filter all night. Still no change in color.
I really dont think my wallet can handle buying all of those chemicals again. I still have a quart of algaecide left but I need to buy some more shock. Before I spend another fortune on Leslie's Chlorbtire...Does anyone out there have opinions on the best shock for your money- or any way to treat this second outbreak?
I think I am spending too much on Leslie's Chlorbrite shock and its not as effective as I would hope. I have a vinyl liner pool but its old and we've used strong shock before (power powder plus) without problems.
