Seachem Flourite is an all natural porous clay gravel substrate, specially broken and mineral-enriched to enhance live aquarium plant growth. It requires no gravel modifiers and never needs to be replaced, remaining effective for the life of the aquarium.

• Premium natural substrate for the planted aquarium
• Good for life of aquarium, no replacement necessary
• All natural porous clay composition

Though its appearance is best suited for planted aquariums, Flourite may be used in any aquarium. It is most effective when used alone as an integral substrate bed, but it may also be mixed with other gravels. Flourite is not chemically coated or treated, and will not alter the pH of your aquarium water.

Directions: Flourite is pre-washed, but may be rinsed before use to remove any residual dust. Residual dust can also be minimized by filling the aquarium slowly while evenly dispersing the water to avoid disturbing the Flourite bed. Some slight initial cloudiness is normal and will clear quickly, within 2-12 hours. Mechanical filtration and Seachem Clarity can be used to resolve cloudiness even more quickly.

Tip: To minimize cloudiness from residual dust, place Flourite in a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed.

Note: This package does not feature a mesh bottom.

CaribSea Eco-Complete Planted Aquarium Substrate is mineralogically and biologically complete substrate for planted aquariums that comes in live water that contains purifying bacteria.

• Mineralogically and biologically complete substrate
• For planted aquariums
• Comes in live water that contains purifying bacteria

Mineralogically complete means it contains iron, calcium, magnesium, potassium, sulfur plus over 25 other elements to nourish your aquatic plants. It contains all the mineral nutrients needed for luxuriant aquatic plant growth without nuisance algae. This iron-rich substrate eliminates the need for laterite.

Biologically complete means it contains live heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants; creates a natural biological balance which makes cycling a new aquarium faster and safer; packed in Liquid Amazon buffered "Black Water" solution for immediate organic water conditioning; unsurpassed MacroPorosity for healthy roots and bacterial efficiency. You would need to buy 4 bags of ordinary gravel to equal the surface area of this one bag of substrate.

Other features include: nitrate and carbonate free-will not increase pH or carbonate hardness; there are no artificial dyes, paints or chemical coatings; the natural black substrate encourages the most vibrant coloration in fishes and reduces fish stress; spherial grains for optimum diffusion performance; supplies calcium without raising the pH; lead free.

The Bi-Modal grading naturally separates into 2 distinct layers: 1) Fine layer on the bottom for best root development and 2) Coarse layer on top which conveys oxygen and nutrients to the roots.

Instructions: Use 1-2 pounds per gallon of aquarium water. Two pounds or more per gallon will deliver best performance. An ideal depth is at least 3".

It is designed to be a complete substate but may also serve as a bottom layer with your choice of non-carbonate substrate on top (do not use marble, dolomite, limestone, crushed coral, shells aragonite etc.).

For new aquarium set-ups simply pour in the entire contents of this bag and fill aquarium with de-chlorintated tap water or, for best results, de-ionized or distilled water. It will automatically segregate into 2 distinct layers with the finer material on the bottom.

For established systems, drain and discard most of the liquid contents of the product before placing into the system.

Warning!!! Placing new gravel over the top ("capping") of an estabished gravel bed can be damaging to aquatic life. Gently mix new material into the existing bed with fingers. For added safety this process can be done, in sections, over the course of a few days.

Place aquatic plants with roots deep into the substrate. Plants may be held in place with the aid of small rocks, pieces of wood, etc.
