Hi everyone. I have a 18x36 concrete and fiberglass inground pool. I had no choice but to drain it this year. The pool is drained all the way except the part over the main and I scooped all the leaves etc out of it. It’s still cold in Indiana. No live algae. I’m at a point where I’m confused. I used pumps to drain it and not main drain. With the small amount of standing water at the 9ft bottom, what do I do with it? Should I start filling it and then when it’s time start my normal routine because it’s black water? I’ll be brushing etc as it’s filling, but should I not drain that last black water with the main drain? This was my exhusbands part of the pool and I’m the chemical one so bear with me. I know the danger of draining it but there wasn’t a choice. Any advice would be greatly apparently appreciated and soon because I’m coming up on 4 days empty
