I have begun the dreadful process of opening a pool that hasn't been opened in 2 years and to top it off the cover has been off for over a year. The pool is a 24' 52 round pool with a vinyl liner and Hayward pump that had all new sand replaced this year. Starting off the pool was basically a swamp, by hand I skimmed the debris and funky green algae clumps off the top, then I shocked the pool and started the filter running 24/7. The next day it was a lighter green color, I shocked it again and continued to let it run. I then took a sample into the pool store for guidance. They told me to add 8 gallons of chlorine because it was barely showing any and algaecide. I did this, took another sample in, the ph was high so I added 5lbs ph down, more chlorine and then added a stabilizer the next day per their recommendations. The chlorine level has still remained low it seems regardless of how much I add and about half way down the water is so cloudy I can't see anything. I have constantly backwashed and swept. What can I do here! Please help with any tips or tricks! Also, is there a good product or good algae brush to help the discoloration on the sidewalls for a vinyl liner? Thank you!!
