ELEMENTALS TRACE Cr - Chromium 250ml

Fauna Marin ELEMENTALS TRACE Cr is a high-purity chromium solution for correcting confirmed chromium deficiencies in reef aquariums.

• Dose: 1ml per 100L (26 US gal) raises chromium by approximately 0.5µg/L
• Maximum daily increase: 0.5µg chromium/L per day
• Target range: 0.1-0.3µg/L; natural seawater reference is effectively 0µg/L (undetectable)
• Ingredients: water, inorganic chrome salts, stabilizers
• Format: 250ml bottle

Chromium supports fat-metabolism enzymes and fatty-acid processing in coral tissue, but the working range is extremely narrow and typically already covered by feed and the rest of the ELEMENTALS/Balling Light lineup. It's also one of the easier trace elements to accidentally overdose — sources like cement-based rock adhesives and some decorations can push levels up on their own — so Fauna Marin recommends against routine individual dosing except to correct a lab-confirmed shortfall.

Includes: 1x 250ml bottle.

Compatible with: dose via the Fauna Marin DIY Doser adapter; only dose after a Fauna Marin ICP test confirms a genuine deficiency.
