Works fine with Windows 7. :lol:

I forgot to mention the stains are almost completely gone..

so I just went to the pool place and had my water tested. these are my levels according to them tc 4.0 ph 8.0 ta 110 ch 300 cya 100 They told me to add alkalinity to raise it.. The only problem I have with that If I add baking soda, it is also going to raise my PH. Is the PH safe or do I need...

yes I have a sand filter. The tc holds overnight and I added 2 jugs of it last night and you were right the stains seems to be fading.. Thanks so much for your help. When they are completely gone, I will update the pics..

the results came from the pinch a penny when I took them a sample, I retested it here my self today and I tested the cya to be about 80 and tc 4 and ph 7.6 and ta 150 the stains look like they are fading compared to last week. Does the cya need to be lowered.

:cry: I have this nasty stain at the bottom of my pool in several places, the pool company is trying to tell me it is black algae but from everything I have read black algae can not grow in above ground pool because it has nothing to root into. the water is clear. i have put a chlorine tablet...
