The fill water can be acidic. Hm, by "drop" you mean going from 7.8 to 6.8 or lower? If you use jumbo tabs that could be making your pH to lower to off scale readings. Note: if your test kit or solutions are old or have been left outside for even a day or less they could be rendered useless and give you false readings. The phenol red solution should be a strong redish color. The solution for chlorine readings should be clear not yellow - if yellow, then discard - no good. If you have just recently added stabilizer ( CYA ) you may get a temp. bad reading.
Check your water with a fresh or new test kit and solutions or take the water in for the pool store to test for comparisons. Take your test kit with you so that the store can compare your kit with theirs. Be sure to take the water sample from the pool just before you head for the store. If you take the sample from the pool in the morning and don't do to the store until that afternoon or the next day - that sample is useless to the store. The sample has to be fresh.

Can a glass jar break if dropped from height in a swimming pool?
It depends on how high you dropped the glass jar into the swimming pool. If you drop the glass jar from a few feet above the swimming pool, it will not break. If you drop it from several stories above the swimming pool, the immense pressure on the glass jar that the water is exerting will cause the jar to break.

What can neutralize chlorine in a swimming pool?
Sodium thiosulfate. You can purchase at pool stores. If for the purpose of draining the pool water to the streets or sewer system you need to neutralize the chlorine or just let it drop on it's own to those levels needed. If on the other hand you have in access of 10.0 ppm chlorine then wait a few days for those levels to drop at their own rate. Otherwise, the water is safe even at 10.0 ppm. to swim in.
