This summer I have not been able to keep chlorine in my pool, I have had a bought with Red algae two times this summer and I am spending about 400+ dollars a month on chemicals.
I have been told that the nitrates in my water are above the action plan of 10ppm, I have owned a pool all of my life and I have need experienced this type of problem.
I life in a rural part of the Eastern Shore in MD, there is an 30+ acre farm behind our home and the farmer did plant corn this year. The gal at the pool store told me I am using 100% more chlorine due to the high nitrate levels, and the only way to fix this is empty the pool and refill with nitrate free water.
Any advice would be greatly appreciated as I am at my wits end,I have never had this type of problem and the pool is starting to become a financial burden.
