Captiv8 Reef BluePrint – Phosph8 (60 mL, 355 mL) — Precision Phosphate (PO₄³⁻) Supplement for Marine/Reef

Overview

Phosph8 is a clean, highly soluble inorganic phosphate supplement designed to correct ultra-low PO₄ and stabilize nutrient balance in modern reef aquariums. Maintaining a small, consistent phosphate level supports zooxanthellae metabolism, coral coloration, polyp extension, and a healthier microbial community—especially in ULNS systems with heavy export (skimmer, refugium, GAC/GFO).

Key Features

• Ultra-pure, reef-safe phosphate—mixes clear with no dyes or perfumes

• Fine control for micro-adjustments; ideal for SPS-dominant systems

• Helps prevent “zeroed nutrients” issues (pale tissue, stalled growth, nuisance dinos tied to starvation)

• Plays nicely with carbon dosing and trace programs when used as directed

• Two sizes for nano to large systems (60 mL dropper, 355 mL bottle)

Directions & Dosing

Always test PO₄ before and 30–60 minutes after dosing. Typical mixed-reef targets: ~0.02–0.08 ppm (tune for your system).

1. Start low: Add 1 drop (~0.05 mL) per 25 gal (95 L), wait, and re-test.

2. Creep to target: Repeat small additions until your target is reached.

3. Stabilize: Maintain with daily micro-doses based on your tank’s consumption rather than large, infrequent additions.

4. Application: Dose into a high-flow area or sump; avoid simultaneous dosing with high-pH additives—separate by 5–10 minutes.

Pro tips

• If using GFO or other PO₄ binders, reduce/temporarily remove while raising PO₄; media can instantly strip additions.

• Do not use alongside lanthanum chloride flocculants.

• If PO₄ overshoots, pause dosing and rely on export/water changes until you’re back in range.

Compatibility

• Safe for corals, clams, and reef-safe fishes when used as directed.

• Compatible with Ca/Alk/Mg regimens, bacterial supplements, and carbon dosing (monitor your NO₃:PO₄ balance).

Ingredients

• Ultra-pure inorganic phosphate in purified water.

Storage & Handling

• Store at room temperature, away from light. Do not freeze.

• Shake gently before use. Keep out of reach of children and pets.
