We have had our pool for about 6 years now and have had off and on issues with green algae. Up until 3 weeks ago, we have always been able to get control and have crystal clear water. We have shocked and shocked to no avail. Our pool used to be shaded and now we have full sun ( we cut the tree down).
I tested the water this morning using our K-2005 test kit
pool size is 20X40 lagoon style in ground vinyl liner
Temp is 85
We are just really stumped, we have put in algaecide, shocked the pool, backwashed the filter, added water. We have had several weeks now of high temps, high humidity and a fair amount of rain.
Any advice is appreciated.
