Reef Charge

C⁶ - Fuel

$16.99

Size

C⁶ - Fuel supplies a clean, bio-available carbon source to feed and expand populations of beneficial bacteria in reef and marine aquaria. By providing the energy these microbes need, C⁶ - Fuel drives natural nutrient export, converting excess nitrate and phosphate into microbial biomass that is removed through skimming and filtration. Regular use helps maintain water clarity, stabilize nutrient ratios, and support the overall health of corals and reef inhabitants.

Instructions

Nitrate control: Dose 1 mL per 100 L (≈ 0.01 mL per US gal) daily, adjusting as needed to maintain nitrate between 5–15 ppm.

Phosphate control: Dose 1 mL per 100 L daily when phosphate exceeds 0.15 ppm. Monitor nitrate to avoid imbalance.

Bacterial support during cycling: Dose 1 mL per 50 L (≈ 0.02 mL per US gal) with an ammonia source to accelerate bacterial establishment. Stop once ammonia and nitrite remain at 0 ppm.

Dose into a sump or high-flow area. Overdosing may cause bacterial blooms, oxygen depletion, or nutrient swings, monitor closely.
