Has anyone else had crazy readings from API Calcium in their bots? I have tried regular and High Res and they both return about the same. Yes, I know API are not the most accurate and can swing high and low, but that is not the issue in this case.
I use Tropic Marin for Nitrate/Nitrite, API Calcium, Phosphate, Mag and Alk are Red Sea Pro. I have manually tested everything my Lab tests, and have gone to two different LFS and had my water tested with same sample. Everything was with different kits. Everything is within margin of error with the exception of the API Cal in the bot. First store used an API Aquaspin and surprisingly came back a little on low side for Mag and little lower in the cal, but the Cal still came back closer to "true". The bot does stay consistent with it's readings, but always low.
First LFS - Aquaspin
Mag 926
Cal 350
Second LFS
Mag 1080-1100
Cal 380
Manual Test
API Cal - 400 (used a total of 3 different reagent kits, 1 from bot and 2 refills)
Mag 1080
Bot
Mag 1060
Cal 280 (Used the original batch in bot, swapped out 60ml bottles with 20ml bottles and reagents from different refill box)
(also tried normal and high res test and all came back about the same)
Also, it seems like the bot is reading "final color" too early sometimes as seen in the picture. It says 290, which is purple, blue isn't achieved until 30 or maybe 31. Granted that doesn't help much and would still be low, 300-310. Just curious if others have seen this in theirs.
