Flourite is a uniquely fractured, stable porous clay gravel designed specifically for natural planted aquariums. While its aesthetic is ideally suited for planted setups, it can also be utilized in any freshwater aquarium setting. Flourite performs best when used solely as a foundational substrate, though it can be combined with other types of gravel. KEY FEATURES: High-quality natural gravel for planted aquariums Supports the longevity of the aquarium SET-UP: Although Flourite comes pre-washed, being a natural product means it may accumulate dust during shipping and should be rinsed prior to use to eliminate any leftover particles. When filling the aquarium with water, do so gradually to prevent disturbing the Flourite substrate. Position a bowl in the tank and pour water directly into the bowl, allowing it to overflow gently onto the gravel bed. It’s normal for the water to appear cloudy at first. To clear up the cloudiness, utilize mechanical filtration (like filter floss). You can also use Clarity to speed up the clearing process.Expires on 20 Nov 2028

Flourite Black is a unique, specially fractured porous clay gravel designed for natural planted aquariums. While it is ideally suited for planted tanks, it can also be utilized in any freshwater aquarium setup. Flourite Black works best when utilized as the sole substrate layer, although it can be blended with other gravels. There’s no need for additional gravel modifiers like laterite. KEY FEATURES: High-quality natural gravel for planted aquariums Supports the longevity of the aquarium SET-UP: Even though it comes pre-washed, Flourite Black is a natural material and may accumulate dust during shipping, so rinsing it before use is recommended to eliminate any leftover dust. When filling the aquarium with water, do so gradually to prevent disturbing the Flourite Black substrate. You can place a bowl in the aquarium and pour the water directly into the bowl, allowing it to overflow gently onto the gravel bed. It's normal for the water to appear cloudy at first. To clear the cloudiness, employ mechanical filtration (like filter floss) and consider using Clarity to speed up the process.

Flourish Nitrogen is a highly concentrated (15,000 mg/L) mixture of nitrogen sources. It supplies nitrogen in both the nitrate form and the preferred ammonium form for plants. KEY FEATURES: Nitrogen booster for planted aquariums 15,000 mg/L blend of nitrogen sources Delivers nitrogen in both nitrate and ammonium forms DIRECTIONS: Beginner For every 160L (40 US gallons), apply 2.5mL (half a cap) twice a week, or adjust based on signs of nitrogen deficiency (such as stunted growth or chlorosis). If you require smaller doses, keep in mind that each cap thread equals roughly 1mL. Expert The beginner dosage increases nitrogen by an amount equivalent to 1 mg/L nitrate. This amount can facilitate roughly 4g of dry growth or about 20g (hydrated) over the course of a month, provided all other essential nutrients are available. For enhanced growth, use a proportionately larger amount. To achieve a specific nitrogen increase, follow this formula: 0.25vn=m, where v represents the tank volume in gallons, n is the desired nitrogen increase (if using a "nitrate equivalent" for "n", apply a factor of 0.05 instead of 0.25 in the formula), and m is the product volume to be used 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 20 Jun 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 enhancement for planted aquariums 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 (such as stunted growth or dark green plants). Expert: The beginner dosage increases phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The optimal phosphate level can vary, typically falling between 0.15-1.0 mg/L. To achieve a specific phosphate increase, use the formula: 0.8vp=m, where v= volume of the tank in gallons, p=desired phosphate increase, and m=amount of product to apply 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 20 Nov 2028
