Ok so we bought this house and it has a pool. A green pool. The plumbing on the pump and filter needed repair so we fixed it. Now the motor is loud (i've ordered a new one) and the ph is super high in the pool. I have no clue what is in the bottom of the pool and believe it is either 12 or 14 ft deep. I am thinking that it would just be easier to drain and start over even though I have managed to get it from swamp green to light green. Thoughts?
