Hi all! I'm in my second season of pool-ownership. The previous owner taught me about TFP and gave me the TF-100 test kit, which I've refilled. I've found this website invaluable. I had essentially no issues with the pool my first season...thank you to everyone here at TFP.
This summer, something doesn't seem right. The water is clear, but I just can't get that trouble-free "sparkle."
My pool seems to be consuming much more chlorine than before. I've been keeping the SWG at 50-60% just to maintain FC, which is higher than I had to keep it last year. I have some small splotches of greenish-brown sediment settling along the creases of the vinyl liner. The stuff brushes away easily (the polaris just fluffs it around) but it re-settles in the exact same places within a few hours or overnight. I had to go through a SLAM a couple of weeks ago because my pool water turned into light green tea, and the pool floor had yellowish dust all over it. I'm not sure if this sediment means that I am still battling algae, or if it's just dirt. I passed the OCLT last night.
I'm considering raising CYA to see if that helps with FC retention. I've held off in case I needed to do another SLAM. We've had lots of hot sunny weather here in Alabama, and my pool is in full sun for 7-8 hours.
I'm also considering another SLAM in case this sediment means there is still algae. What would you do?
