Each of the past two years I noticed small beads on the pool floor and in the cleaner towards the end of the season. Not recognizing them, it took me a bit to figure out what they were. In each case it was the mineral cartridge, which had split a bit on the side allowing the mineral beads to be pushed into the pool. Because it was the end of the season - I didn't make a big deal of it. Well - year 3 using Nature2 and this time the split has happened mid season. Three in a row takes away the coincidence possibilities. Any ideas of what might be causing this?
I have read a few of the threads on these mineral cartridges and now understand that they may not be a good idea and I will be thinking about that. For now - I'd like to try to understand why this is happening.
