Modern Reef All-in-One Reef Keeping System (RKS) | Reef Engine Core 7.7x High Concentrate

Take total control of your marine aquarium parameters with the ultimate proportional consumption dosing system. The Modern Reef All-in-One Reef Keeping System (RKS) Reef Engine Core 7.7x High Concentrate is a complete, ultra-concentrated 4-part liquid solution designed to simplify reef management. Formulated and proven by Akil at Euro Corals to grow and propagate spectacular corals, this system delivers all essential macro-elements, trace elements, amino acids, and micronutrients in balance with your aquarium’s daily usage.

By linking trace element delivery directly to Alkalinity (KH) and Calcium uptake, Reef Engine Core 7.7x eliminates the need for endless individual supplementation and constant multi-parameter testing. Just test and monitor your KH—the system calculates and takes care of the rest.

Key Benefits for Your Reef Setup

• Vibrant Coral Pigmentation: Developed specifically to stimulate challenging yellow and orange pigments while drastically enhancing red, pink, blue, and purple coloration across SPS and LPS corals (especially Acropora species).
• No More Constant Ca/Mg Testing: Once your baseline consumption is established, you only need to monitor Carbonate Hardness (KH). The 4-part mix keeps everything else in perfect proportional balance.
• Clutter-Free Sump & Dosing: Replaces standalone bottles of amino acids, independent trace element mixes, or separate coral growth boosters. Everything your corals require for skeletal structure and tissue health is included.
• Enhanced Water Clarity: Promotes the natural propagation of cryptic filtration organisms like sponges and sea squirts, polishing your water natively.
• Ultra-Pure Formula: 100% free from Nitrates (NO₃) and Phosphates (PO₄), ensuring zero unwanted nuisance algae fueling.

Choose Your Pack Size

This 4-part system is available in three convenient, ready-to-use volumes tailored to your tank’s demands:
• 4 x 500ml Set: Perfect for nano tanks, standalone frag systems, or hobbyists looking to trial the Modern Reef methodology.
• 4 x 1000ml (1L) Set: Ideal for mid-sized mixed reefs and standard home setups.
• 4 x 2500ml (2.5L) Set: The cost-effective choice for heavily stocked SPS-dominant displays and large volume reef systems.

Precision Concentration & Dosing Guide

• Concentration Profile: 10ml per 100 Litres of aquarium water will raise your Alkalinity by 2 dKH.
• Preparation: Ready to dose right out of the box—no mixing or magnetic stirrers required. Store in a cool, dark place away from direct light (ideally in its original dark canisters).
• Dosing Method: Designed for use with a calibrated 4-head dosing pump. For optimal stability, program equal parts to be dosed with a 10–15 minute gap between channels (e.g., KH1 → CAL → KH2 → MAG).
• The Modern Reef System: For maximum growth, polyp extension, and cellular vitality, pair this core foundational block with Modern Reef Complete Reef Food (CRF) and Polypop (PP).
