You may have already read this somewhere, but just a reminder.... I have glass tile under my sheer descents like you do. If your water has a tendencey to leave scale on your shower door and coffee pot, then under the sheers is the place most likely for it to happen on your pool. I wasn't vigilant enough with mine, because I didn't think about it. I run my water features only 10 minutes a day to keep chlorinated water going through the pipes and pumps. But that was enough for my glass to end up with quite a bit of scale during the second year. It's been difficult to remove, but the glass looks much better now. My plan is to keep on top of it and give those areas a more frequent going over than my waterline tile.
All your colors are so perfect together; it looks like a magazine. The glass tile, waterline tile, fire glass, pool color.... even the sky in your pictures is cooperating with matching the blues of your pool!! What color PebbleTec did you go with? Be sure to add that to your signature for future newbies who fall in love with your pool!!!
Enjoy!
