Aquavitro Eight.Four is a precision pH and alkalinity buffer designed specifically for marine and reef aquariums. It safely raises pH to 8.4, replenishes carbonate alkalinity (KH), and is formulated to avoid overshooting pH levels. Eight.Four is phosphate-free and highly soluble, making it ideal for maintaining a stable, natural reef environment and supporting the needs of corals and invertebrates.

Key Features

  • Raises and maintains pH at 8.4
  • Increases carbonate alkalinity (KH) for buffer stability
  • Phosphate-free formula – won’t fuel algae growth
  • Highly soluble and fast-acting
  • Safe for all marine and reef inhabitants
  • Designed for regular use or pH corrections
  • Ideal companion to Aquavitro Ions and Calcification

🧪 Usage Instructions

Initial Setup

  1. Shake well before use.
  2. Dose 5 mL per 80 L (20 US gallons) to raise alkalinity by 0.5 meq/L (1.4 dKH).
  3. Add slowly to a high-flow area of the sump or aquarium.
  4. Test pH and alkalinity before and after dosing.
  5. Avoid raising alkalinity more than 1 meq/L (2.8 dKH) per day.

Maintenance Dosing

  • Dose as needed to maintain pH at 8.3–8.4 and alkalinity at 7–11 dKH.
  • For stable systems, this may be every 2–3 days or as dictated by coral and biological demand.
  • Use alongside Aquavitro Calcification (calcium) and Aquavitro Ions (magnesium) for a balanced reef chemistry routine.

Frequently Asked Questions (FAQ)

Q: What does Eight.Four do in a reef tank?
A:
It raises and stabilizes pH and alkalinity, helping prevent dangerous pH swings and promoting coral health and biological filtration.

Q: Can I use Eight.Four daily?
A:
Yes, it is safe for frequent or routine use—just ensure that alkalinity changes are gradual and monitored.

Q: Will this product increase calcium or magnesium?
A:
No. Eight.Four specifically targets carbonate alkalinity and pH, and should be paired with Calcification and Ions for calcium and magnesium needs.

Q: Can I overdose Eight.Four?
A:
Excessive use may cause pH or KH to rise too quickly, stressing livestock. Always test before and after dosing and adjust gradually.

Q: Is Eight.Four safe for soft corals, SPS, and invertebrates?
A:
Absolutely. It is reef-safe and balanced for all types of marine life when used correctly.

Q: How is Eight.Four different from other buffers?
A:
It is designed to lock pH at 8.4, is phosphate-free, and offers a fast-dissolving, high-purity formula ideal for reef applications.

Q: Can I mix Eight.Four with other Aquavitro supplements?
A:
Yes. For full mineral stability, use in conjunction with Balance, Calcification, and Ions depending on your tank’s needs.
