First let me start by saying I switched to the BBB method last year (after being a Pristine Blue user - which seemed to stop working for me) and my pool has never been cleaner, clearer, and/or more sparkly. Plus, testing & adjusting daily is so easy!
Now, to my question. I have some friends who bought a new house w/ an above ground pool - about 18,000 gallons...sand filter. I tested their water which started out almost black and helped them get it clean with BBB. He recently had to work the wheat harvest here in Oklahoma and at times did not get home to 3:30 am.....and hence ignored the pool for about a week. He discovered it was somewhat green.......shocked it twice.......and backwashed and now it is cloudy. His FC is at 4 and his ph 7.5. So, I am not sure what is causing his cloudiness. I have been trying to talk them into buying an auto vacuum as he has been manually vacuuming every 3 or 4 days. Any suggestions for them to try?
