is this normal?

[aylad]

i just opened the pool yesterday and found about 200 dead worms and a couple of other dead critters at the bottom. despite the dead stuff the water was fairly clear. before adding anything to the pool i brushed and let it filter about 24hrs. i tested the water and had these numbers- fc 0 ph 7.0 ta 50 cya 25-30. the pool is 12,000 gal inground vinyl liner with an aquarite swg. this morning i put in about 5 gallons of bleach waited a few hours and tested again with these results- fc 30 ph 8.0+ ta 50. is this normal for the ph to rise like it did? what should i do next? the water is crystal clear. thank you.

After your chlorine level comes back down and you verify that the pH is still in the normal ranges, I would use a little baking soda to get the TA up to around 100, then go swimming!
