I have restrained myself from posting my pool issues in the hope that things would evenually work out, but I have been struggling with greenish pool water for over 7 weeks now. First a little background...
I underwent the Baquacil to BBB conversion on my 24 foot above ground pool when I opened it Memorial Day weekend. I did not treat the water last fall when closing the pool, anticipating this spring's conversion. I did have to add at least 1/3 fresh water in order to get the skimmer running. The water was clear. Bacquacil tests showed 0 levels. The conversion went well, quickly running through the various (and much anticipated!!) color changes. The water never did leave the slightly green tint stage however.
Over the past 7 weeks I have read and reread all posts and sticky's regarding treating of my pool water. I have raised chlorine levels to shock levels several times and maintained them at these levels for well over a week each time. I purchased a TF-100 kit and have already had to order a refill for the FC/CC tests. CC numbers have ranged from 0 - .5 but never higher. I changed out the filter sand after the conversion was completed and backwash as needed. I also have brushed the pool repeatedly.
My current numbers are as follows (taken at 11:00 PM):
FC 3.5 (was 6.0 24 hours ago)
CH (not tested since this is a vinyl liner)
The CYA level is a little surprise for me tonight since it had been around 42 or so. I did add muriatic acid to lower my PH earlier today, though I'm not sure if this would have any effect. I'll have to test it again.
Any thoughts on how to get to the sparkling clear water everyone in the family is anxious to see??
