I've had to empty my ~15K gallon gunnite/glass pool to replace the water. It had so much sodium in it that I was concerned that I couldn't use it for drinking water in an emergency, and the phosphorous and CYA were off the charts (din't have much trouble keeping the algae out, tho -- just used LOTS of bleach!)
While it is empty, I have some small ~3/4" underwater decorative tiles on some steps and sets that have come loose (I still have the tiles.)
What kind of grout is recommended for to re-set the loose ones?
Also, I had my gunnite pool fiber glassed a good ten or 15 years back. It is holding up nicely, however, a spot in the jacuzzi, while still intact, seems to be pulling up, as I can definitely hear a void when it is rapped with the knuckles. Should I worry about this? It's been this way for at least five years.
If so, is this something I might be able to repair myself? The work had a 20 year warranty, but big surprise! The contractor declared bankruptcy, so out went the warranty. I'd PAY the *** to come and fix it, but he doesn't answer my inquiries.
