Red Sea Reef Care 4 Part Rcp Small 150ltr

Description

Red Sea Reef Care 4 Part RCP Small 150-litre — Maintains trace elements (Calcium, Magnesium, KH/Alkalinity) in reef tanks up to 150 litres

Red Sea Complete Reef Care 4-Part RCP Small (SKU: RED876) is a streamlined, complete supplementation system engineered to maintain optimum foundation parameters (Calcium, Magnesium, KH/Alkalinity) and trace elements in reef tanks up to 150 litres.

The Complete Reef Care program is a simplified, yet comprehensive 4-part supplement system designed to ensure optimal coral growth and colouration in reef aquariums without refugiums. By replenishing all 36 major, minor, and trace elements, including alkalinity components, this system allows hobbyists to maintain a thriving reef while simplifying their dosing routine.

The program is ideal for systems where a refugium is not present. For reefs with refugiums, the traditional 7-Part Reef Care program is recommended to allow precision dosing tailored to both corals and the refugium. Based on Red Sea’s long-term research into coral skeletal growth, this system ties the consumption of all 4 parts directly to a single Calcium test measurement, eliminating the need for constant, complex multi-element testing.

The 4 parts are formulated in an easy-to-implement ratio:

• Part 1: Calcium, Magnesium, Strontium, Barium
• Part 2: KH/Alkalinity components
• Part 3: Potassium, Boron, Iodine, Bromine, Fluorine
• Part 4: Iron, Manganese, Cobalt, Copper, Aluminum, Zinc, Chromium, Nickel plus 18 additional bioactive trace elements

Usage & Application

When to Use

• Complete Reef Maintenance: Supplies all required foundation and trace elements for mixed or SPS reef aquariums.

• Simplified Testing: Best for aquarists who want full element balance based on testing only Calcium.

How to Use

1. Perform a weekly Calcium test to determine system consumption.

2. Calculate the required Part 1 (Calcium) dose.

3. Dose Parts 2, 3, and 4 in equal or calculated ratio as directed by the RCP dosing chart.

Product Specifications & Highlights

Key Features

• Simplified 4-Part System: Covers Calcium, Alkalinity, Magnesium, and essential trace elements.

  The 4 parts are formulated in an easy-to-implement ratio:

  • Part 1: Calcium, Magnesium, Strontium, Barium

  • Part 2: KH/Alkalinity components

  • Part 3: Potassium, Boron, Iodine, Bromine, Fluorine

  • Part 4: Iron, Manganese, Cobalt, Copper, Aluminum, Zinc, Chromium, Nickel plus 18 additional bioactive trace elements

• Calcium-Tied Ratio: Dose calculations are derived directly from Calcium consumption. Calcium serves as the key indicator of coral growth. A single weekly measurement determines the correct dosages for all four parts, simplifying monitoring and dosing. By dosing according to calcium uptake, the system ensures optimal availability and stability of all elements for coral growth and colouration.

• Fixed Ratio Supplementing: Research shows that in reef tanks without refugiums, the 36 elements and alkalinity components are depleted in a relatively fixed ratio, allowing all elements to be dosed according to calcium uptake.

• Automatic Dosing with ReefDose: Once connected to the ReefDose system, adjusting the daily dose of Part 1 (Calcium) automatically adjusts Parts 2- 4. The four parts are balanced so they finish at the same time, ensuring convenience and efficiency.

• Prevents Ionic Imbalance: Formulated to maintain natural seawater ionic ratios over time.

• Sized for Nano/Small Tanks: Perfect starter pack for systems around 150 litres.

Coral Growth & Colouration

• Foundation Elements: Calcium, Magnesium, and Bicarbonates form the basis of water chemistry, pH stability, and coral skeleton formation.

• Minor & Trace Elements: Essential as biocatalysts in metabolic processes and coral pigment production. Correct dosing prevents toxicity while supporting vibrant colouration.

• Accelerated Growth: Balanced elevated levels of foundation elements increase aragonite saturation, allowing corals to build skeletons faster and more efficiently.

• Colour Enhancement: Maintaining balanced nutrient levels and controlling algae populations helps reveal natural coral pigments, producing brighter and more vivid colouration.

Why Dose by Calcium, Not Alkalinity

While alkalinity is used in coral calcification, measuring total alkalinity can be misleading:

• Total Alkalinity includes contributions from borates, phosphates, sulphates, and organics that do not directly reflect coral skeletal growth.

• Dosing based solely on alkalinity risks overdosing calcium and trace elements, causing precipitation and destabilising water chemistry.

• Calcium measurement directly correlates with coral growth, ensuring precise supplementation without disrupting the chemical balance.

Program Benefits

• Simplified Routine: One weekly calcium measurement dictates all dosing.

• Balanced Ratios: All 36 elements and alkalinity components are replenished in proper proportions.

• Optimised Coral Health: Supports skeleton formation, pigmentation, and overall metabolic activity.

• Convenient & Efficient: Compatible with ReefDose for automated dosing, reducing human error and saving time.
