Hello to All,
I have spoken to someone about a month ago about the stuff collecting in the bottom of the pool.It appeared brown or black when I first logged on here.My water chemistry was way off at the time,and has since been much more balanced.I have also added a SWG to the system. I have since treated the pool with algaecides,which made it turn grayish/white,then eventually brown/black on the edges.the stuff will keep coming back to the exact same spots in the pool within a day of being brushed.The water is crystal clear.
Here are the latest test results using a Taylor K-2005:
FC-3PPM,TC-3PPM,CC-0PPM,PH-7.8--8.0,ALK-110PPM,CYA-70PPM,SALT-4400PPM.The FC level varies some,depending on the type of day.Most are full sun all day with temps in 95/105 range every day.
I am going to treat this as a Mustard Algae issue and I am ready to nuke the pool with liquid chlorine.My questions are these.
1) Is my water balanced properly for this ?
2) How long will I be out of the pool before it is safe to swim again-ballpark figure.
I am going to use the pool calculator linked to you site for the amount of Chlorine to add.The pool is 18x36x8.5 from which I base a figure of approximately 27k gallons.
Any insight or help you can give me here will be appreciated.
