+++ on water changes and maybe take a sample of your water to your local lfs to test for you.

I personally use the Hanna checkers for dkh, calc, pH and salinity. Red Sea pro for phosphate, pH, nitrate and nitrite if I test those and to double check the Hanna checkers. They're pretty reliable

I heard mixed on the Ca checker. so it’s been pretty reliable? what is the difference to titration test check?

couple points, i'll take some pics later. A lot of people don't use it correctly and come up with skewered results, myself included until I actually learned how to use it.

I use the Hanna Ca also. Every once in a while I compare it to a Salifert test and they are always within 25ppm of each other. For me that is close enough. I aim for consistency rather than a specific number.

I would suggest having more than one brand test kit to check your results every so often, especially if you get a reading that seems way off.

Calcium test kits has about 10% error to begin with. But calcium level is not that critical as long as it is about 350ppm and below 500 ppm. It makes little difference within the range.
