A few weeks ago the water temp went through the roof and started turning green. That's the first time in over 4 months. I gave it a good hit of Shock and surprisingly it was clear the next day. Now I just give a hit of Cloro out of the bottle every morning and it's doing fine even with big crowds.
I gave up doing the chemical testing for PH and CL. It just didn't seem to be doing anything for my knowledge or helping the pool. I will get some more Shock but adding acid in any form was just a waste of time and money. I stopped by the local pool store to see what could be done for vacuuming and the kid that works there gave me the best tip. Just get about 4 meters of 3/4 or 1" hose, get it siphoning and suck out the stuff on the bottom. Good excuse for me to get into the pool. Every time you vacuum the level goes down so a chance for some fresh water.
