Flourish Nitrogen is a potent (15,000 mg/L) mix of nitrogen sources. It delivers nitrogen in both the nitrate form and the ammonium form that plants prefer. KEY FEATURES: Nitrogen booster for your planted aquarium 15,000 mg/L blend of nitrogen sources Supplies nitrogen in both nitrate and ammonium forms DIRECTIONS: Beginner Administer 2.5mL (half a cap) for every 160L (40 US gallons) two times a week or as required based on signs of nitrogen deficiency (e.g., slow growth, yellowing leaves). For smaller amounts, be aware that each cap thread is roughly 1mL. Expert The beginner dosage increases nitrogen by the same amount as 1 mg/L nitrate would. This dosage is adequate to facilitate approximately 4g of dry growth or around 20g (when hydrated) over the course of a month (assuming all other essential nutrients are supplied). For enhanced growth, use a proportionately larger amount. To achieve a specific nitrogen increase, follow this formula: 0.25vn=m, where v= tank volume in gallons, n=desired nitrogen increase (if using a "nitrate equivalent" value for "n", utilize a factor of 0.05 instead of 0.25 in the formula) and m=amount of product to apply in mL. For instance, to elevate 20 gallons by 0.20 mg/L nitrogen, you would calculate: 0.25*20*0.20=1mL.Expires on 05 Aug 2031

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
