2 part brand? Nano

Calcium is low at around 300 hence the main reason for switching brands to keep it up, I do weekly water changes at half gallon in the 6 gallon nano. Actual water volume with live rock and sand at about 5 gallon. So will see how it goes once I dise with Esv thogu. Thanks

Regardless of the brand, and assuming that is not a measurement error, I'd suggest bringing it up over a few days with a one time correction. Then go back to normal calcium and alkalinity dosing.

Could be a measurement error but also an outdated kit perhaps, I just order the Red Sea kit for calcium alk and mag.
It just arrived so will test tomorrow with an update.

Sounds good. Let us know what you find.

What salt are you using for your water changes, BTW?

I forgot what brand my lfs uses but it's pretty decent as far as visually seeing the corals response. My other test kit must have been crap/old because
Red Sea shows my calcium at 430 and Mag at 1400 alk will retest it today because I screwed up. So far so good but hoping once Esv bionic gets here
I will visually see a much better response in my tank.
