I need all the help I can get

Me and my husband (military) just rented a house with a pool. .

By the way it looked when we moved in, I don't think it has been covered or messed with in the past couple years. The water was pretty much black. We did manage to remove the millions of leaves and other debris. And it has been shocked. so its debris free now and a light green color.

He managed to get the pump working but i'm pretty sure it was just trial and error. and now he is gone and I have NO idea what to do :)

We have a Hayward S-220T sand filter and solar industries pool heating system.
I have been watching videos and I just cant figure it out and I really don't want to mess something up.

Anyway, any help would be great.

Thank you!

Hi Its;

Welcome to the wonderful world of man-made slime pits! Sounds like you made substantial progress toward turning it back into a pool!

I'm going to give some 'get-by-for-now' advice; do NOT confuse with the 'how-you-can-best-run-operate-your-pool' advice we'll try to give later, once we know more!

FIRST: send the best and biggest pictures you can, of your pool, your pipes, and your equipment, to poolforum@gmail.com. We can give better advice once we know exactly what you've got!

SECOND: Verify my assumptions: (1) your pump and filter are operating now; (2) you are planning to use chlorine, and don't have some chlorine-alternative chemicals in the pool; (3) you haven't recently added a bunch of well water to your pool. If my assumptions are correct, go to step THREE. Otherwise, tell me what IS correct.

THREE:
+ Go to Walmart, today if at all possible, and get 12 gallons of plain 6% household bleach -- generic is fine; scented is not -- AND a cheap OTO/phenol red drops based test kit.
+ Before you add the bleach (below), test the pool.
+ Pour 2 gallons of bleach into the pool. (Don't splash it on yourself: bleach isn't very toxic to people, but it's very toxic to clothes!) Either pour it on top of the return stream re-entering the pool OR pour it in multiple spots around the pool. Plan on doing this EVERY evening till you know more about the pool.
+ Post the test results here; tell us the dimensions of your pool if you know.
