Do you know what your GH is?

Assuming the reading on your test kit to be correct .Adding a handfull of shellgrit to your tank would help to keep your water more stable, and prevent pH crash.

ladyred the reading is correct tested it 4 times.will the shell grit affect my ph? thanks for the help. GH is 50ppm.

It will help to buffer the pH and keep it stable. i.e. it won't drop so rapidly.
