DIY fluorine

[wopper]

Hi everyone,

I’m looking to create a DIY fluorine supplement (matching the Reef Zlements / Reef Lab concentration).

My target is a solution where 10 ml of solution increases fluorine by 0.2 mg/L in 100 litres of tank water.

I have pure Sodium Fluoride (NaF, 41.99 g/mol).
AI suggested dissolving 4.42 g NaF in 1000 ml RODI, but I’m not fully confident in the calculation.

Could someone please verify whether this is correct, before I kill something ?
Thank you!
