First let me say this is a great site! I have been reading for days and have learned a lot but feel I am as lost as day one. We left our Intex pool (20’ x 4’) alone all winter long and now it’s all green. We started by renting a pump and draining all the water except for about 3” of water (hose could not get the rest). Then we filled it back up and added a box of “green to blue” from Wal-Mart. That turned it from green to gray. We tested the water and everything was way off. We added 7lbs of ph minus and it lowered it down to 8.0. So we added another 7lbs and now it’s down to 7.5. Then we added 5lbs of shock to get the chlorine up with no luck. That’s when I started reading on this forum and entered my readings into the pool calculator.
I printed the page of everything it says but I think I need to kill the algae. Water is still a milky color. So I read defeating algae and how to shock your pool. Do I need to get my CYA up before I start the shock process? With my test readings it says to add 120oz of bleach. Is it okay to add that much bleach at one time? Also during the shock process how much bleach should I add every hour?
Any help would be greatly appreciated and needed.
