DYMAX Crystal CO2 Indicator

DYMAX Crystal CO2 Indicator

DYMAX Crystal CO2 Indicator is a clear, in‑tank CO₂ monitor that shows real‑time dissolved CO₂ levels in your planted aquarium. DYMAX Crystal CO2 Indicator works with an indicating solution to give a more accurate CO₂ reading than bubble counting alone, helping you avoid both CO₂ deficiency and dangerous overdosing.

PRODUCT Details

DYMAX Crystal CO2 Indicator is designed to make CO₂ monitoring in planted aquariums simple, visual and accurate. Instead of guessing from bubble counts, this glass‑style indicator uses a special solution to show the actual CO₂ level dissolved in your tank water.
Because CO₂ is one of the key elements for plant growth, using DYMAX Crystal CO2 Indicator helps you keep levels in the sweet spot—high enough for lush growth, but not so high that it becomes dangerous for fish and shrimp.

Why DYMAX Crystal CO2 Indicator Is Important

From the product details, DYMAX Crystal CO2 Indicator addresses several key points:
  • CO₂ is essential for plant growth – insufficient CO₂ leads to poor, stunted growth
  • Over‑supply of CO₂ is dangerous – too much CO₂ can stress or harm fish and other aquatic life
  • Bubble counters only predict CO₂ – they show gas flow, not how much CO₂ is actually dissolved in the water
DYMAX Crystal CO2 Indicator works with an indicating solution to provide an accurate reading of CO₂ dissolved in water, making CO₂ monitoring more efficient and reliable than bubble counting alone.

How DYMAX Crystal CO2 Indicator Works

DYMAX Crystal CO2 Indicator is a small device that sits inside the aquarium:
  • The indicator is filled with a CO₂ test solution (indicator solution)
  • CO₂ from the aquarium water diffuses into the air gap inside the indicator
  • The solution changes colour depending on the CO₂ concentration
  • You can then read the colour (typically blue/green/yellow range) to judge if CO₂ is low, optimal or high
By using DYMAX Crystal CO2 Indicator alongside your bubble counter and regulator, you get a much clearer picture of what your plants and fish are actually experiencing.

Benefits of Using DYMAX Crystal CO2 Indicator

Adding DYMAX Crystal CO2 Indicator to your planted tank setup can:
  • Provide real‑time visual feedback on CO₂ levels
  • Help prevent CO₂ deficiency that slows plant growth
  • Reduce the risk of CO₂ overdosing and stress to fish and shrimp
  • Make fine‑tuning your CO₂ system easier and more confident
  • Complement your bubble counter and regulator for a complete CO₂ control system
For anyone running pressurised CO₂, DYMAX Crystal CO2 Indicator is a simple, affordable safety and optimisation tool.

Using DYMAX Crystal CO2 Indicator in Your Aquarium

General usage steps for DYMAX Crystal CO2 Indicator:
  • Fill the indicator with the recommended CO₂ indicator solution (as per product instructions)
  • Invert carefully to avoid spills and attach it inside the aquarium, usually with a suction cup
  • Position below the water surface but in an area with gentle flow, away from direct CO₂ bubbles
  • Allow 1–2 hours for the solution to equilibrate and change colour
  • Adjust your CO₂ bubble rate and timing based on the colour reading (aiming for the “optimal” green zone)
Regularly check DYMAX Crystal CO2 Indicator during the photoperiod to keep CO₂ stable for your plants and safe for livestock.
