Calcium dropped.

dadart2028 · Jul 17, 2023

Hello,
I have a 105-gal tank, and it's been running for a year and a half now. I am using Kalkwasser 6 grams per gallon, dosing it via Kamoer 2.7ml/min for 12hrs, and dosing a Calcium reactor 10.4 ml/min for 12 hours. I changed my Reagent B-C for apex trident yesterday, and lately, my calcium has been reading low. Also, I did a 15 gal water change last night. I need to figure out what's going on. Do I Need to test calcium separately with a different testing kit? Any Suggestions would be appreciated.

If you have coraline and or your corals are growing calcium is consumed.

Think the trident is outta whack! Might need to be calibrated or repaired.. if you’re running kalk it would be high! Never that low lol

Do you have a regular test to check it? Such as salifert etc?

Test it with those and see.. abc reagents quit selling calibration solutions and recommends using your favorite test kits to get your numbers from your tank and program them into the trident for calibration for better results.

I’m having the opposite problem with kalk lol.. my new regents came today so I’ll try and calibrate it tonight hopefully and see. I got salifert test kits myself.
