Hi Aylad

I use test strips....... with that said I'd say i'm somewhere between30 to 100 on stabilizer as it fluctuates week by week, pool has full sun from 9:30am till about 6:30pm. I also just bought 3" tabs from Walmrt, just started using them 10 days ago and my numbers seem to have dropped. I seem to have a difficult time with these color strips, though my daughter zero's in on the color pretty quicky, which made me laugh last night after i read tips and tricks on your other site.

Thanks,
-Rob
