ELEMENTALS B - Boron 1000 ml

Fauna Marin ELEMENTALS B is a concentrated boron solution formulated to correct boron deficiencies identified by reef aquarium water testing.

• Dose: 15ml per 100L (26 US gal) raises boron by approximately 1mg/L
• Maximum daily increase: 2mg boron/L per day
• Target range: 4-5mg/L (natural seawater level is ~4.5mg/L); SPS-dominant, high-light systems often run 5-6mg/L
• Format: 1000ml bottle, gentle correction method

Boron supports cell membrane growth and stability, contributes a small share of the carbonate buffering system, and plays a role in coral pigmentation and contrast. Deficiency below roughly 2mg/L can cause bubble-like tissue detachment; because the therapeutic window is narrow, dose conservatively and re-test rather than chasing the top of the range in one step — an overdose can harm corals.

Includes: 1x 1000ml bottle.

Compatible with: dose via the Fauna Marin DIY Doser adapter for direct-draw automatic dosing; pairs with a Fauna Marin ICP water test to confirm actual boron levels before dosing.
