I just mixed some VDB traditional last night using

Part A
33ml distilled water
9g Ferric Ammonium Citrate

Part B
33ml distilled water
1.5g of Tartaric Acid

Part C
33ml distilled water
3.8g silver nitrate

I got a milky white precipitate down the bottom of my bottle..is this unusual, should i filter this off before use?
