Seachem Flourite Black (7 kg/15.4 lbs) Premium Natural Substrate For The Planted Aquarium | Aquatic Plant Fertilizer(7 L)

DIRECTIONS: Although it is pre-washed, because Flourite??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Black is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust. NOTE: The specialized mesh bottom of the 3.5 kg size allows it to be rinsed right in the bag., TIPS: When adding water to aquarium, fill slowly to avoid disturbing Flourite Black substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity to accelerate clearing. For an even stronger root zone and enhanced growth rates, add a 2.5 cm (1 inch) base layer of Onyx Sand to your aquarium before adding Flourite Black.
