Problem: VERY GREEN WATER, 2wks plus
My pool: 12,000 gallons
Pool chemicals: started with 3 bags of super shock/ then tried soda ash to bring ph up above 8 (per leslies') & green to clean then added 5 more bags of super shock
My pump & filter: sand filter
Other info: we have done a partial water change for the past 7 days everyday (1 foot a day to waste and refill). Have vacummed several times and backwashed 3 times.
We are new pool owners , pool is 18yrs old, has been maintained effeciently in the past by professional pool company. We took over the maintainence 6 wks ago, about 2 wks ago, the automatic chlorinator ran out of tablets for about 2 days, at the same time we had a thunderstorm that blew in a lot of pollen and the tree in our neighbors yard started blooming and dropping pollen in the pool. Since then the water has been a lovely shade of green, going from a light shade (margarita green) to now a very dark (kelly green) shade . We started with leslie's recommendation of partial water change - 1 ft drain to waste/refill (did this 4 times) . We have also daily been diligent in removing all debris, etc. and cleaning out the skimmer. Still green, leslie's recommended that we use soda ash to bring ph above 8, super shock, add "green to clean", shock again and then vacume. Still green, and now seems to be a darker green (kelly green). Leslie's now says to dump to waste at least 4 ft of water to bring down the CYA, and told us that "she didn't have a clue what else to do" which is very scary to a new pool owner (what the h*** do you do when the pool store doesn't know what to do?!?!? )! Hoping you guys can help us out! Hubby is about ready to fill it in with dirt or make a skate park outta the pool for our son!
