Let me start off with my test results.
I go out today and there is visible algae on the walls and floor of the pool. I always dose chlorine to about 8 and it drops to around 5 in two days. My target FC is 4. It never goes below that. I have no idea how algae is growing. I test my water every other day. It never shows any CCs. I am conpletely stumped as to how this happened. I did lose power for a week a couple weeks ago but i kept the chlorine high around 8-10, brushed the pool daily and made the family get in daily to move the water around. Again, never registered any CCs in the water. Circulation looks good as I watched a leaf floating near the bottom and it was moving all over. How is this possible?
Does a solar cover promote the algae growth? You guys always said if you keep the chlorine levels right algae cant grow.
