Aqua Essentials Presents - Aquarium CO2 Drop Checker

1. Aqua Essentials Presents: Aquarium CO2 Drop Checker Precision monitoring for thriving aquatic ecosystems www.aquaessentials.co.uk

2. Why Monitor CO2 in Your Aquarium? The Delicate Balance Carbon dioxide is absolutely vital for lush plant growth and maintaining fish health in planted tanks. However, achieving the right balance is crucial—too little CO2 stunts plant development and allows algae to flourish, whilst too much endangers your fish by depleting oxygen levels. Precise CO2 control prevents algae outbreaks, promotes vibrant plant growth, and creates a thriving, balanced ecosystem where both flora and fauna flourish together harmoniously.

3. What Is a CO2 Drop Checker? Glass Reservoir Colour Indicators A small, elegant glass chamber containing a special pH-sensitive indicator solution Changes colour to show CO2 levels: blue (low), green (optimal), yellow (high) Visual Monitoring Provides a simple, at-a-glance way to monitor dissolved CO2 without guesswork or testing

4. The Science Behind the Colour Change 01 02 Indicator Solution CO2 Diffusion Contains Bromothymol Blue combined with a fixed carbonate hardness of 4 dKH for standardised readings Carbon dioxide gradually diffuses into the drop checker's sealed airspace through the water interface 03 04 pH Alteration Optimal Reading The dissolved CO2 alters the pH of the indicator solution, triggering a visible colour transformation Green indicates approximately 30 ppm CO2—ideal for plant photosynthesis whilst remaining safe for fish

5. How to Set Up Your Aqua Essentials Drop Checker Fill the Reservoir Fill the glass chamber halfway with the included indicator solution (4 dKH + Bromothymol Blue) Submerge Carefully Insert into your aquarium below the water surface, positioning away from direct CO2 bubbles Secure in Place Attach with the suction cup to the glass where water circulation is good and viewing is easy Wait for Stabilisation Allow 1–2 hours for the colour to stabilise and provide an accurate reading before making adjustments

6. Interpreting the Colours & Adjusting CO2 Blue: Low CO2 CO2 levels too low for optimal plant growth Action: Increase your CO2 injection rate gradually Green: Optimal Perfect CO2 concentration around 30 ppm Action: Maintain current settings—your tank is balanced Yellow: High CO2 CO2 levels dangerously high for fish Action: Reduce CO2 immediately to protect fish health

7. Best Practices for Accurate Readings Optimal Placement Avoid False Readings Position your drop checker where water flow is strongest to ensure proper CO2 mixing throughout the indicator solution. Strong circulation provides the most representative reading of actual tank conditions. Never place directly in the CO2 bubble stream from your diffuser, as this creates artificially high readings that don't reflect true dissolved CO2 levels in the water column. Regular Maintenance Be Patient Replace the indicator solution every 3–4 weeks, or sooner if it becomes cloudy or contaminated. Fresh solution ensures reliable, accurate colour changes. Remember that readings reflect CO2 levels from 1–2 hours prior, not real-time. Allow sufficient time after adjustments before interpreting results.

8. Common Troubleshooting Tips No Colour Change? Check your CO2 diffuser placement and verify tank circulation is adequate. Poor water movement prevents CO2 from reaching the drop checker. Persistent Yellow Warning If yellow colour persists, add aeration immediately and reduce CO2 injection to protect fish. Monitor fish behaviour closely for signs of distress. Gradual Adjustments Adjust bubble rate gradually—typically 1–3 bubbles per second works well for tanks up to 200 litres. Make small changes and observe results over several hours.
