Seachem CO2 Indicator Solution 50ml

Seachem CO2 Indicator Solution 50ml
Perfect for planted aquarium enthusiasts, Seachem CO₂ Indicator Solution is the refill reagent designed exclusively for the Seachem Glass pH Checker (drop checker). This colour-changing solution lets you continuously monitor dissolved CO₂ levels in your planted tank at a glance, so you can maintain the ideal CO₂ balance for lush, vibrant plant growth while keeping your fish safe.
Simply add to your glass pH checker, and watch the colour shift to reflect your tank’s CO₂ concentration: blue signals low CO₂, green marks the optimal target range, and yellow warns of excess CO₂ that can stress your livestock. Skip complicated test kits and guesswork; this reliable reagent delivers constant visual feedback for your CO₂ injection system.
Ideal for all planted aquariums running CO₂ setups. The handy 50ml bottle provides plenty of refills for long-term aquascape maintenance.
