So thankful I found this site when I first stared with pools a few years ago. Finally decided to take the plunge and become a member because you've all been so helpful.
Sadly, we did not winterize or pool last year and we had to drain/start fresh. We did convert to an intex SWG in the process, though! Recently, I've been wondering if we should have replaced the sand in our filter??
We got all set up about 3 weeks ago, then went on a week long vacation and returned to quite a bit of algae a week ago (I guess I thought the SWG would prevent that on it's own). I treated that and thought we were good to go. However....
The SWG has consistently read "low salt", but when I had the water tested (pool store) a week ago, the chlorine read super high. All my other numbers were perfect.
We also have some bad staining on the bottom. Today, I did the "vitamin c test" and the stains immediately lifted anywhere we placed the tablet. Ascorbic acid: is this also sold as "lemi-shine"?
Here are my readings today, using my hth test strip and small drop kit (I know, I know--I'd like to use these up before I have to buy something else and I always have the pool store as a last resort):
BR-8.8 (can someone explain what this is?)
-------so how bad am i?--------
