I noticed yesterday afternoon my water looking a bit yellow. I tested the water and the results were:
I had done an AA treatment for iron staining on my liner a couple weeks back and since then the FC had dropped low a few times so, thinking this was organic I brought the FC up to shock level. A few hours later the water began turning darker and this morning it is green.
The TA has been running low from the AA but that is about it.
I fertilized my yard with a phosphorus-free pre emergent yesterday AM and also added lime to the the lawn, however I have been doing this twice/year for 7 years and have not had any problems as I am always careful to stay well clear of the pool.
I don't normally believe in coincidences but I can't see how I could have contaminated the water. The timing does seems strange though.
Otherwise, no heavy rains in the past few days or any thing else out of the ordinary. Thoughts and comments would be greatly appreciated.
