I’m having a brain fart due to lack of sleep. I had a few questions about dosing the Trace Colors. So we’re supposed to dose 1 mL for every 20 ppm of Calcium added to 100/L or 26.4/G of aquarium water.

I’m not sure I know how many ppm of Calcium I’m adding. I know what my Calcium level is @ 440ppm & I’m dosing 24mL daily on my new system that’s about 8 months old.

So given that information how will I determine how many mL’s of my Calcium dose is equal to 20 ppm of Calcium added for my water volume of about 75/G’s.

So would this calculation be right:

93.7mL of ESV = 20ppm

153.5mL of BRS = 20ppm
