We purchased a house last fall, and the previous owner had partially drained the pool, shut down the pump/filter, and covered it in mid-August. I pulled the cover off yesterday (fearing what I would find), and it is a swamp! This is my first experience with a pool, so I have been reading/researching (and will continue to) and generally understand some of what needs to happen. I know I have to get the filter running before I can attack the algae (I'm guessing I'm going to need to clean it both before AND after getting things under control). However, I can't even see the walls well enough to know where the winterizing plugs are - and I can't start the filter and pump without doing that.
So, what do I do? Do I...
1. Try to mix enough shock in there manually to try to clear up the water enough to see?
2. Drain the pool to below the plug levels and then refill (I'm guessing it's a 30k gallon pool and it is full, so I would HATE to have to do that).
3. Some other option I don't understand or know?
I welcome any insights on this!
