Oh Look, none yet written anything at the moment. I have changed last year of CO2 on carbonaceous fertilizers. Had because of the great reviews first use Easy Life Easy Carbo, but could not share the euphoric results. I then alternatively Hs Aquaflora Carbo tested and stuck with it. It has advantages: + Only once a week fertilize necessary + 5 mL per 50 L water required! (Cap measuring cup) + Cloud the water less + Plant growth perfectly fine algae growth previously not recognized + Fish and snails it is outstanding! - Cap (Turn + Push) is tricky / unpractical. I can find nothing negative to date and stick to it. Therefore 4 stars from me.
What the manufacturer states: In addition to all the necessary trace elements and fertilizers Flora Carbo also contains a natural non-hazardous carbon component for optimal growth of your plants without CO2 system. Also applicable to shrimp, crabs and snails ornamental.
