Hydrogen Protocol Calculator

How This Ramp Up Calculator Works

This calculator estimates how long it takes to raise dissolved hydrogen from 0 ppm to your target concentration when starting with water that contains no hydrogen. It is designed specifically for the initial “ramp up” phase — the period when you are first introducing hydrogen into a system that currently has none.

How the Calculation Works

The model first calculates the theoretical minimum amount of hydrogen gas needed to reach your target ppm in the given tank volume. It then applies your selected loss multiplier to account for real-world off-gassing caused by surface agitation, protein skimmers, high flow, and gas exchange. This gives a more realistic estimate of how long each pulse mode will take.

Diffuser Hardware & Placement Options

Your choice here directly affects how efficiently hydrogen gas is transferred into the water. Here is what each option represents:

• Standard Open Diffuser (0.50%) — Basic diffuser releasing hydrogen bubbles freely into the water column with no containment or directed flow. This is the lowest efficiency baseline due to rapid bubble rise and minimal contact time.
• Simple Bubble Cup (1.00%) — Diffuser used inside a basic inverted bubble cup or trap. The cup provides modest containment, slightly increasing contact time compared to an open diffuser, but with limited mixing.
• Powerhead / Below Pump Intake Placement (1.50%) — Diffuser positioned directly under a pump intake so bubbles are pulled into the pump. This improves capture and contact over a simple bubble cup through active flow into the pump.
• In-Tank Filter + Media (Ceramic Rings) (3.50%) — Diffuser placed at the bottom of an in-tank filter beneath the pump intake, with ceramic media above it. Bubbles naturally drift upward through the media while the pump pulls water upward through the same path, creating strong turbulence and extended contact.
• Dedicated Reactor (BRS Mini / Similar) (5.50%) — Diffuser placed directly under the pump feeding a dedicated reactor (such as a BRS Mini Reactor). Water is forced through the reactor chamber, providing improved gas-water contact and higher dissolution efficiency compared to standard media reactors.
• Dedicated Reactor (BRS Standard) (8.00%) — Diffuser placed directly under the intake of a larger dedicated reactor pump (such as a BRS Standard Reactor). The pump pulls water and microbubbles into the reactor chamber, providing the highest dissolution efficiency currently supported. No media is used in the chamber.

System Dynamics / Flow Level Options

This setting adjusts how aggressively hydrogen is lost from your system due to water movement and surface agitation. Higher flow and more surface disruption cause hydrogen to off-gas faster. Choose the option that best matches your tank’s actual conditions:

• Quarantine & Calm Water (1.25x) — Very low flow, minimal surface agitation. Best for dedicated quarantine tanks.
• Freshwater / Planted Aquascape (1.35x) — Moderate flow typical of planted or gentler freshwater systems.
• FOWLR (Fish Only Marine) (1.50x) — Moderate to high flow with standard marine equipment.
• Standard Mixed Reef (Active) (1.65x) — Typical reef tank flow with protein skimmer and normal surface agitation.
• High-Energy Reef (Extreme Flow) (1.85x) — Very high flow, strong surface agitation, and aggressive gas exchange equipment.

Pulse Mode Conversion

• Micro (5 min ON / 25 min OFF) = 16.7% duty cycle — Gentlest mode with the slowest, steadiest increase
• Light (10 min ON / 20 min OFF) = 33.3% duty cycle — Light daily support with a moderate ramp-up rate
• Balanced (15 min ON / 15 min OFF) = 50% duty cycle — Good everyday balance of speed and stability
• Performance (20 min ON / 10 min OFF) = 66.7% duty cycle — Strong output for faster daily results
• Extended (25 min ON / 5 min OFF repeating loop) = 83.3% duty cycle — Highest output mode with frequent short breaks for consistent gas-off

How This Ramp Up Calculator Works (Flow-Through Unit)

The Elite is a closed-loop flow-through system. Unlike diffuser-based systems that inject hydrogen gas directly into the aquarium, the Elite dissolves hydrogen into a recirculating water stream inside the unit and then delivers already-dissolved hydrogen-rich water into the tank. This design achieves significantly higher effective dissolution than traditional bubble diffusion methods.

Dissolution Efficiency and Real-World Performance

The Elite uses a fixed 15% overall dissolution efficiency. This value accounts for both the internal performance of the unit and the losses that occur once the hydrogen-rich water enters the aquarium. Real-world factors such as surface agitation, protein skimmers, high flow rates, and gas exchange equipment reduce the amount of dissolved hydrogen that remains in the system. The 15% figure represents a conservative estimate of net performance across a range of typical aquarium setups.

Recommended Pump and Flow Rates

The Elite is designed to be used with a dedicated fixed-speed 120 gph pump. Two hydrogen production flow rates are supported: 150 ml/min and 300 ml/min. These rates provide good flexibility while maintaining reliable performance with the recommended pump.

Important Note on Pump Flow: The Elite is calibrated for use with a dedicated 120 gph pump. Using a different pump flow rate will affect the actual dissolved hydrogen concentration delivered. Lower pump flow generally increases concentration, while higher pump flow may slightly reduce it.

System Dynamics / Flow Level Options

This setting adjusts the estimated hydrogen loss rate based on your tank’s water movement and equipment. Higher flow and more surface agitation cause dissolved hydrogen to leave the system faster. The multiplier increases the amount of hydrogen you need to add to reach your target concentration:

• Quarantine & Calm Water (1.25x) — Very low flow and minimal surface disruption. Lowest hydrogen loss rate.
• Freshwater / Planted Aquascape (1.35x) — Moderate flow typical of planted or gentler freshwater systems.
• FOWLR (Fish Only Marine) (1.50x) — Moderate to high flow with standard marine equipment.
• Standard Mixed Reef (Active) (1.65x) — Typical reef tank flow with protein skimmer and normal surface agitation (most common setting).
• High-Energy Reef (Extreme Flow) (1.85x) — Very high flow, strong surface agitation, and aggressive gas exchange equipment.
