Description
Modern Reef RKS 7.7x – All-in-One Proportional Consumption System
4x5L Set (KH1, KH2, CAL, MAG)
Take your reef aquarium to the next level with the Modern Reef RKS 7.7x, an advanced all-in-one dosing system designed for maximum stability, coloration, and growth—without complexity.
This highly concentrated 7.7x formula delivers everything your reef needs in a perfectly balanced, proportional system based on KH (alkalinity) consumption.
Why RKS 7.7x?
Developed and tested by reef experts, including Akil from Euro Corals, this system simplifies reef keeping by eliminating guesswork and reducing the need for multiple additives.
Complete Reef Solution
- Includes trace elements, micronutrients, and amino acids
- Covers calcium, alkalinity, and magnesium
- No need for extra supplements
Proportional Consumption Technology
- Automatically balances elements based on KH consumption
- Prevents overdosing and unwanted buildup
- Adapts to any reef system and nutrient export method
Color & Growth Enhancement
- Enhances yellow & orange pigments (traditionally difficult)
- Boosts red, pink, blue & purple coloration
- Improves Acropora body & polyp colors
- Stimulates non-fluorescent chromoproteins
- Designed for blue spectrum reef lighting
Performance Benefits
- Faster coral growth (especially with Complete Reef Food)
- Improves water clarity via sponge & sea squirt activity
- Eliminates need for constant Ca & Mg testing (focus on KH only)
- Free from Nitrates (NO3) & Phosphates (PO4)
Concentration
- 10 ml per 100L raises 2 dKH
Dosing & Usage
Simple Rule:
Dose equal parts of all 4 components.
Target:
- KH: 6.8 – 8 dKH
- Calcium: 380 – 420 ppm
Smart Adjustment:
- If Ca drops → increase dosage (raise KH slightly)
- If Ca rises → decrease dosage (lower KH slightly)
Once stable, no frequent calcium testing needed.
Dosing Tips
- Use a 4-head dosing pump (recommended)
- If using 3 heads → mix KH1 + KH2 and double dose
- Keep tubing equal length for accuracy
- Dose in sequence: KH1 → CAL → KH2 → MAG
- Leave 10–15 minutes gap
- Split dosing throughout the day
Important Notes
- Do NOT combine with other amino acids or trace products
- Store in a dark, cool place
- Avoid direct light (prevents instability & microbial growth)
- No shaking or stirring required
