High pH in cycling tank

[Merdfrog]

I'm on what appear to be the final days of my cycle and I have just had a massive spike in pH. Last I check a few days ago my pH was 8.0 and today it reads 8.8. Has anyone had this problem and is there a reasonable solution.
Thank you!

Probably just an error in the test unless you dosed something

Turns out it was an error after all. I was panicked for a sec

FWIW, any high pH reading (above about 8.5) in a tank not using high pH alk additives is generally test error.
