Natures 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. Natures Ocean recommends using Nutri-SeaWater Natural Live Ocean Saltwater to instantly establish an ideal marine environment.

Note: Not recommended for undergravel filters.
