Losing NO Chlorine overnight. Water temp is at a blamy (haha) 71*F. The water had leaves on the bottom from an overnight windstorm, some pollen on the surface and splotches of what I THOUGHT was debris/dirt on the bottom. I threw in my bot to suck up the leaves and the splotches I thought was debris and now I have a greenish pool!!! I can still see the bottom of the pool, but the water is green. I run my pump constantly, great circulation and now I notice, today, what looks like algae (greenish-yellow) on my steps I was going to take out today. :*( How?!?! I test every other day because I am a freak about my pool and my levels are really good! Could my pH be too high? I am getting ready to order my cover and new pump and, if I have to, new steps. (Nothing wrong with my pump, but it has seen 4 summers of constant running and 2 full winters so I think it might **** out soon.) What should I do? We now have more leaves so I will have to throw the bot in again tomorrow. Does this sound like Algae? BOO TO ALGAE!
