Your levels cannot go up from one day to another without doing water changes or dosing. I would think that your test results are inaccurate.

I would make sure you are being accurate with your testing. Those test results don't seem correct as mentioned above.

Was that test taken after your water change? Only thing that would make them go up without a water change would be the salt, dosing or bad test kits.

I did the second test which I mention up before water change , and it was at moring time , the old test it was before a week after water change and at night time .
There is any reason to have that reading because day and night time ? For Ca , MG and kh ??
And again I dont dose nothing in my tank test kit is salifert and not expire to have wrong test reading

Ph would be the only thing bouncing around between day and night.

That is my thinking also. The other results could well be within the margin of error. But the kh readings are way off.
