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
 
Hi there. Welcome to TFP :)
If you're insisting on getting the remaining water out you could try a wet-dry vac. Or refill the pool and deal with it if it remains a problem. Is it just old decayed leaves causing the dark water? Get any solids out and you can deal with the remaining water. Nothing works better than Liquid Chlorine and a good test kit.
Here are the basics of the TFP method: Pool Care Basics

Provide some more details on why it was drained so we can maybe give you a bit advice. If it’s just decayed leaves that accumulated over the winter, it’s probably fine to leave a tiny bit of water in there and clean it up when it’s full. But something larger than a skunk died in there and caused it to become black then I might want to try and drain all of the water out.
 
Yes, please give us background on the pool. Get in there and clean all the solids out. Bucket it out or shop vac it out if you want but get the solids out. Then get a hose in this puppy and fill it up. In the meantime you need to be reading the following links to be ready for making the pool TFP clean and sanitized. Get your test kit ordered so it's close to being here when the pool gets full. You'll need only liquid chlorine, muriatic acid and some granular CYA for startup.
