Does temperature affect reading?

Does temps affect trident readings? It's a 20ppm difference in reading for calcium. My ALK reads good and way more stable it's more of calcium and mag readings.

Not that I know of. Its more likely the corals being effected my temp and time of day which will cause the fluctuation in Cal.

Why would I get higher readings when i haven't dosed.

I thought you were dosing.

Dosing only ALK. Only time i dose calcium if i go for more than a week without doing a WC

I can't show pictures now as I sent my Trident in to be serviced and it was returned in pieces, so, I will have to send it back again, but I noticed the same. I do dose and I contributed to what I said above about the corals using elements depending on the time of day and temp and such.

I think the person who would know best about this would be @Randy Holmes-Farley.

Don't forget the Trident has a margin of error of +/- 15 ppm for Calcium and Magnesium, and +/- 0.05 dKH for Alkalinity. The increase in Calcium on your graph is within that margin of error. Neptune's graphs always look like there's a large swing because they zoom in. Look at the scale.
