EasyCarbo is a very powerful and effective source for aquarium plants. A strong growth improvement is noticable after 1 to 2 weeks. Usable with or without CO2 addition. Algae will have great difficulties to sustain themselves due to a better plant growth. Very good to combine with the universal fertilizer ProFito. The better growing plants (even Cryptocorynes or Echinodorus sp.) can compete better with algae. e.g. brush algae don't have any change and will disappear within several weeks. Dosage rate: aquarium with only a few plants : 1 ml per 100 litres daily. Aquarium moderately planted : 1 ml per 50 litres daily. Aquarium heavily planted : 1 ml per 25 litres daily.

Follow API Easy Care Guide and use the pH TEST KIT:
During Regular Care
When addressing Water Problem Solving issues
Taking a few minutes each week to maintain and monitor aquarium conditions is the key to a healthy aquarium. pH control is imperative to prevent the harmful effects of overly alkaline or acidic aquarium water on fish and plant life. Fish require a specific pH level to thrive. However, pH in an aquarium can fluctuate due to fish waste, addition of tap water and the build-up of natural acids. Use this kit to easily and accurately measure the pH level and maintain a healthy freshwater community aquarium. For use in freshwater aquariums.
