Hi Ben,

I wonder if I can hijack my own posting? Here goes...

As mentioned earlier, I'm trying to clear the water so I can refill it and dye test 5-6 vertical hairline cracks located around the sidewalls, and generally running 12" to 30" below the normal surface of the water.

It's a concrete pool with a quartz plaster finish. The cracks are so fine that you can NOT even catch your fingernail on them. So the options:
1. Run some clear silicone over them, for now
2. Cut out a narrow slit, the width of a small diamond blade, and fill it with plaster
3. Epoxy the surface ,,,or some combination of the above

Right now, I'm wanting to trouble shoot the leaking and don;t mind doing something temporary until I can verify if these cracks are the source of the leak. I'd rather not just fill it without at least trying something on the cracks initially.

Any ideas/ suggestions are much welcome!
