Hey guys, just out of curiosity do any of you have similar experiences with ph being significantly lowered after seachem prime was added. Nothing else is done
In the last few days I dose two prime twice, the first time was after a 40% water change, my ph and orp fell off the cliff immediately.
After two days I dose again without a water change to test. It reacts the same. Ph went from 7.4-7.2 and orp from 320-200 ish.
Ph probe was calibrated 2weeks ago. Although I haven't calibrated my orp probe in a while, its accuracy is not important, all I needed is that's it shows a huge swing like this. I will attach my pax reading as references below

This is a 190 system Africans cichlids tank, its been up for little more than a year with no plants and auto water change.
Water parameters are usually very very stable. I did a 40% water change because I was so bored that day and decided to do one ...... nothing else is done.
Any ideas are appreciated. Thanks
