here you go: FC - 5 PH - 7.4 CYA - 55 TA - 70 CH - 280 Water is crystal clear.

I put 6-8 pucks on the plaster floor a few inches apart, leaving for 3-4 hours with good effect -- the stains cleared. It was a slow process, but after a few days I was able to take care of about 25% of the pool. During this time, I turned by SWG to 0% as I was getting plenty of FC from the...

Yes, I have a Polaris 280 and I had that theory as well, but I can't see how the fairly soft wheels of the cleaner would cause the issues (especially when brushing with the wire brush seems to have no effect). I think it had more to do with the differences in the final plaster finish caused by...

Perhaps my photos don't show it very well (documented in this tread scaling-t35405.html), but your situation is very similar to what I'm dealing with in a recently re-plastered pool. In looking at my chemistry log, it's not clear how I got here, but I've concluded that I'm dealing with scale of...

I think I'm dealing with the same issue as the original poster -- those photos look very similar to my situation (see my thread scaling-t35405.html) I left a chlorine puck on some affected areas for about 4 hours and noticed considerable improvement. But, now I'm not sure how to attack the...

Real time update.... After leaving a chlorine tablet on top on a portion of the affected areas for about 4-5 hours, the stains have lightened considerably. What does this tell me and how can I effectively go about treating the entire pool (20'x44')? Current FC reading is ~3.

Is it possible this could be dirt and/or algae that somehow got embedded into the new plaster during the curing process? If you look at my start-up details above, you'll see that my chlorine level was pretty minimal during the first 30 days (less than .5 or so).

Does anyone have any tips on differentiating between normal mottling on white plaster and something worse like scaling?

Ok, here are the gory details: It was a four-man crew (1 working the mixer on the truck, 3 in the pool). Seemed to be fine with no signs of difficulty in working the plaster. Again, the finished looked good and consistent for the first four weeks, then the staining started to appear. And the...

Thanks for the reply. I'm pretty confident that calcium chloride was not added during the plaster process. The project was completed third week of May (temps in the high 70s- low 80s) and I had a very explicit discussion with the plaster crew foreman about this as he was preparing the mix. I...

Sorry for the double post, but I believe I posted my original message in the wrong forum. Here is a link to the original message and pictures. new-replaster-help-me-assess-this-situation-t35357.html Mods, is there a way for me to move this first post to this forum? Just ask :) Topics merged...

Re: New replaster - help me assess this situation Yep, forgot about the Vitamin C test. I did that test and didn't see a change. As one additional data point, I just got back from the local, usually reliable pool store (actual experienced adults working -- not Leslie's). I showed the...

New replaster - help me assess this situation Relatively new pool owner and need help assessing my situation. First, the stats: FC = 4 TC = 4 pH = 7.4 TA = 70 CH = 300 CYA = 60 Just had my IG pool replastered in white as part of a very long, frustrating renovation process (poor contractor)...
