Flourish Excel provides a readily available source of organic carbon. All plants need carbon for growth, which they usually obtain from CO2, but can also be sourced from simple organic materials. KEY FEATURES: Accessible organic carbon source for your planted aquarium Can be used as an alternative to CO2 injection or alongside it Brings in photosynthetic intermediates DIRECTIONS: When using for the first time or following a significant water change (greater than 40%), apply 1 capful (5mL) for every 40L (10 US gallons). After that, use 1 capful for every 200L (50 US gallons) on a daily basis or every other day. For smaller measurements, please note that each cap thread is roughly equivalent to 1mL.Expires on 13 Jan 2030

Flourish Phosphorus is a reliable solution (4,500 mg/L phosphate) of potassium phosphate that eliminates the uncertainty of phosphate dosing. KEY FEATURES: Phosphorus enhancer for your planted aquarium A dependable 4500 mg/L potassium phosphate solution Removes the uncertainty from phosphate dosing DIRECTIONS: Beginner: Administer 2.5mL (half a cap) for every 80L (20 US gallons) once or twice a week, or as necessary based on signs of phosphorus deficiency (e.g. stunted growth, dark green plants). Expert: The beginner dosage increases phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The optimal phosphate level can differ, but typically falls between 0.15-1.0 mg/L. To achieve a specific phosphate increase, apply the following formula: 0.8vp=m, where v= tank volume in gallons, p=desired phosphate increase, and m=amount of product to use in mL. For instance, to elevate 20 gallons to 0.1 mg/L phosphate, you would calculate: 0.8*20*0.1=1.6 mL.Expires on 13 Jan 2030

Flourite is a uniquely processed, stable porous clay gravel designed for natural planted aquariums. Its aesthetic is particularly suited for planted setups, yet it can be utilized in any freshwater aquarium setting. Flourite performs best when used as a standalone substrate, but it can also be blended with other gravels. KEY FEATURES: High-quality natural gravel ideal for planted aquariums Beneficial for the longevity of the aquarium SET-UP: While Flourite comes pre-washed, being a natural product, it might accumulate dust during shipping and may need rinsing before use to eliminate any remaining dust. When introducing water to your aquarium, pour it in gradually to prevent disruption of the Flourite substrate. To do this, place a bowl inside the aquarium and direct the water into the bowl, allowing it to overflow gently onto the gravel bed. It’s normal for the water to appear cloudy initially. To clear the cloudiness, utilize mechanical filtration (like filter floss). For faster clarity, consider using Clarity.Expires on 19 May 2029
