Ideal colour to aim for green. Blue means too little, yellow means too much. Adjust your CO₂ output accordingly.You may also want to consider the 3ml Pipette which is used to dispense the Bromo Blue liquid into the drop checker. If your drop checker stays blue you simply need more CO₂. Simple as that. Show more
