My ph used to be 7.0 but today I tested it and it was high ph 7.4 or 7.6 hard to tell, when I used the regular ph test it was 7.6. The only thing different I have done is give cucumber. All of my tank mates in both tanks love it. I usually leave it for a day or two, I dont blanch it so it does not fall apart. I remove the seeds before I put it in. Would this make my ph rise???????
