Please help! I bought a house with a pool and dont know much about taking care of pools. I just took the cover off and it is a total swamp. I am in the process of filling it up so I can start the pump/filter. What is the first thing I should do once I get the filter going? I have one of those TF-100 test kits but have not used it yet.
Here are some pictures if it helps. As you can see, it is a really dark green but the liner is a light blue :
