I'm new, have been reading posts and have just completed pool school but just want some advice from the experts. I am buying a house with a pool, it isn't mine yet, but will be within a week or so. The owner is out of town and not willing to fund any maintainence on the pool until closing. The pool was being cared for by renters, but since they moved out last week it has gone from gorgeous to green in 2 days, i had no idea it would be this quick! I have permission to get in the yard and do stuff to the pool, but I don't live there as yet, so a full clean is not going to be doable yet. My aim is to try to keep the pool from getting too out of control until we move in and can start doing things properly.
I have added aquachem blue shock in double dose as suggested, cleaned the filter and added chlorine tabs to the automatic chlorine thingie. I'm heading back tomorrow to see what I have and add anything else that it might need. I think i need to add acid to lower the PH and let the chlorine work, but im not sure how much. As I won't be there daily, should I over chlorinate? Shoud i adjust the timer to run for longer? Is there anything else I can do to prevent a horrible situation?
Pool: in ground concrete, 11,000 gallons, cartridge filter.
Water was crystal clear day 1, day 2 was starting to turn cloudy, by day 3 (today) it is green and I cannot see the bottom. I can see the steps, so about 18 in deep.
Water test was strip so limited, sorry: TC very low, FC very low, PH was high, stabilizer very low.
