Now that it seems the shock issue is resolved, we have been cleaning the pool. We had changed covers the last time we covered it and it used water bags. Well, it came a hail storm a couple months ago and busted them all which allowed the cover to fall in and everything that was on it. Now we have this green sludge everywhere in the deep end. So bad that the robot has to be taken out every 1-2 minutes and cleaned. I feel like I’m getting nowhere. How stupid of an idea would it be to drain all of the water, get in and clean the Crud out of the pool, then refill? The chemicals in the pool are very limited at the moment.
