Overview

Drive predictable nitrate and phosphate reduction with carbon dosing done right. Carbon8 aq 8.35 is a high-purity, BluePrint-compatible liquid organic carbon formulated to fuel beneficial heterotrophic bacteria that convert NO₃/PO₄ into biomass for removal via skimming and filtration. Designed for controlled, stepwise adjustments in modern reef systems.

Key Features

• Balanced carbon source — Supports rapid microbial uptake of nitrate and phosphate without harsh swings.

• Clarity & polish — Proper use often yields brighter water and cleaner rock/sand as organics are processed.

• Low-nutrient friendly — Tune small, repeatable daily doses to maintain modest, non-zero nutrients.

• Methodology-ready — Integrates with Captiv8 BluePrint schedules and bacterial programs (Remedi8/Propag8).

• Two sizes — 355 mL for smaller systems/testing and 1006 mL for long-term or high-demand use.

• Doser-friendly — Ideal for automated micro-dosing after careful calibration.

Directions

1. Test first: Measure NO₃ and PO₄. Set realistic targets (avoid absolute zero).

2. Start low: Dose per label for total system volume at ½ the recommended starting dose for the first week.

3. Ramp carefully: Increase in small steps every 3–4 days while watching NO₃/PO₄ trends and livestock.

4. Export matters: Run a reliable protein skimmer and keep mechanical filtration clean to remove new biomass.

5. Maintain: Once targets are reached, shift to a steady daily dose to hold levels. Re-test weekly and adjust.

Important: Avoid rapid nutrient drops. Make changes gradually and base adjustments on test results and visual response.

Best Practices

• Keep core parameters stable: Alk 7.5–9 dKH, Ca 420–450 ppm, Mg 1280–1380 ppm, Salinity 1.025–1.026, Temp 77–79°F.

• Ensure strong aeration/flow; carbon-driven bacterial growth increases oxygen demand.

• Dose at a consistent time each day; log NO₃/PO₄ to refine the routine.

• If nutrients bottom out, reduce or pause dosing and increase feeding slightly to restore balance.

Compatibility

• Works alongside skimmers, carbon, phosphate media (tuned conservatively), UV/ozone (dose away from sterilizers), refugia, and bacterial supplements.

• Space additions from other liquid supplements by several minutes in a high-flow area.

• Not for freshwater use.
