What does everyone who has stairs in an above ground pool do to prevent algae - specifically under the stairs.
I have stairs in my above ground pool, and I use a mat underneath them. Last season I had no problems. However this year, when I pulled the stairs when I closed the pool I found algae (green staining) under the stairs and under the mat.
Nothing during the season indicated any sort of problems. My FC consumption was never out of whack. Once in a while (maybe 2-3 times all season) my CC was above zero, and it was never even 0.5 - just a faint hint of pink.
So what does everyone do to prevent algae? Do you pull your stairs / mat on a regular basis to clean under them? I take care of my pool daily (test and add chem as needed) and brush/vacuum weekly.
