Nature's Ocean Live Reef Sand is premium, 100% natural, bio-active aragonite sand for marine aquariums. Made from real ocean sand, packaged in its natural state, it comes ready for instant use: just add saltwater and fish for instant cycling and a thriving tank.

• 100% natural live ocean sand, packaged in its natural state
• Instant cycling for immediate nitrogenous waste removal and organic balance
• Contains natural live marine bacteria to quickly stabilize your tank

This all natural marine sand contains live beneficial bacteria biofilm - the same cultures that naturally maintain healthy balance in the ocean! It activates immediately upon immersion in saltwater, instantly beginning to remove ammonia, nitrite, and nitrate to establish biological balance. Since these bacteria are straight from the ocean, they are more effective than cultured live sand products that artificially replicate marine conditions. This original patented formula is ideal for most applications*.

In addition to beneficial bacteria, this substrate also provides essential trace elements for healthy coral growth, including zinc sulfate, calcium chloride, manganese chloride, cobalt chloride, copper sulfate, sodium molybdenum, strontium chloride, nickel chloride, potassium bromide, and sodium silicate.

Recommended Use: Use a minimum of 1lb Bio-Activ Live Argaonite Live Sand per gallon of saltwater. Set up an appropriate filtering system and allow it to circulate. During the first month introduce no more than 1" of fish per 5 gallon saltwater. Nature's Ocean recommends using Nutri-SeaWater Natural Live Ocean Saltwater to instantly establish an ideal marine environment.

*Note: Not recommended for undergravel filters.

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.
