    What are these particles floating in the water?

    I've noticed these white translucent particles floating in the water the other night when I had the lights on. They are flat and 2 to 3 millimeters square or rectangular. I can't detect them during the day - only at night just in front of the lights. I noticed it the most after brushing the pool as I probably stirred them up. I can capture them with a net and they are soft and fall apart when touched. I'm guessing its calcium, but my CSI has never ventured out of range (-.6 to .6) and is almost always around -.3. All numbers are in range for a SWG plaster pool. Any ideas? I'll try to get a photo.

    They may be bits of scale from the blades of your SWG.

    That is calcium that is in suspension.

    So is it anything to worry about? The SWG cell has been operating less than a month. It is self cleaning, is in a clear tube and I can't see any build up on it. Possibly it builds up and then flakes off.

    I think the previous posts are educated guesses. If it persists you could try to retrieve some of the flakes and have them analyzed...
