How big is you tank ?
Do you dose kh ?
What is other parameter ?
How long have it been ?
I believe this needed so that at lease they can help. By the way can do water change slowly to bring it down. Big water change may fluctuate too much and cause major problem

Hydrochloric acid.

Slowly drip dilute HCl over the course of abt a day. Or do 3x 30% water change with low alk salt every 3-4 hours.

Tbh i quite skeptical of your results. If i got such high reading first thing i do is get a new test kit. Maybe the pH indicator in the test kit expired or smth.
