Fritz RPM Calcium Buffer System Pt 2 Calcium

Introduction

Fritz RPM Calcium Buffer System Pt 2 – Calcium is a concentrated liquid supplement formulated to support the calcium demands of reef and marine aquariums. As a key component of the Fritz RPM 3-Part System, this product helps maintain optimal calcium levels—essential for the growth and skeletal development of corals and invertebrates. Used in conjunction with Pt 1 Alkalinity and Pt 3 Magnesium, it ensures a balanced and stable reef environment, promoting vibrant coral coloration and long-term health.

Features

• Supports Coral Growth – Supplies bioavailable calcium to promote the development of strong coral skeletons and healthy invertebrates.

• Part of a Complete Buffer System – Designed to work synergistically with Fritz RPM Pt 1 (Alkalinity) and Pt 3 (Magnesium) to maintain key parameters in balance.

• Concentrated, Fast-Dissolving Formula – Ensures efficient calcium supplementation without clouding or adverse effects.

• Prevents Calcium Deficiency – Helps avoid instability in calcium levels that can hinder coral health and tank balance.

• Reef-Safe – Suitable for all marine aquariums, including systems housing sensitive corals and invertebrates.

Directions & Dosage

Adjustment Dosage:

• Shake well before use.

• Test calcium levels before dosing.

• 1 mL raises calcium by 15 ppm per 1 US gallon (3.78 L).

• 5 mL (1 tsp) raises calcium by 7 ppm per 10 gallons.

• Do not exceed 10 mL per 10 gallons per day.

Routine Dosing:

• Ensure alkalinity is adjusted to 8–11 dKH before starting routine dosing.

• Begin with 5 mL (1 tsp) of Pt 1 and Pt 2 per 20 gallons of water daily.

• Maintain calcium levels between 400–450 ppm by testing and adjusting as needed.

• Increase dosage if calcification demand is high (e.g., in SPS-heavy tanks).

Best Practices:

• Dose into a sump or high-flow area to ensure even distribution.

• Use reliable calcium test kits for accuracy.

• Cloudiness is normal—wait for it to clear before adding other components.

• Safe for all marine livestock, including invertebrates.

• 4 oz, 8 oz, and 16 oz bottles use a 5 mL cap; 32 oz bottle cap = 10 mL.

Important Note:
If magnesium levels are too low, calcium and alkalinity may precipitate as calcium carbonate. Always ensure magnesium is in range (1250–1350 ppm) before adjusting calcium or alkalinity. Use Fritz RPM Pt 3 – Magnesium to correct magnesium levels first.

Available Size

• 473 mL / 16 oz

Recommendations

For best results, use Fritz RPM Calcium Pt 2 as part of the complete Fritz RPM system, including Pt 1 Alkalinity and Pt 3 Magnesium. Consistent supplementation and water testing are vital to achieving a healthy, thriving reef tank. Balance between calcium, alkalinity, and magnesium ensures optimal coral growth, coloration, and long-term system stability.
