## Description

desertcart.com : Nature's Ocean Bio-Activ Live Aragonite Reef Substrate, 8 lbs : Aquarium Decor Gravel : Pet Supplies

Review: Nice sand - I bought this sand for my refugium connected to my 75 gallon reef tank. It is a nice substrate that did not cloud the water longer than an hour after adding it (I have had other sand substrates cloud the water for days, literally). I had no problems planting my macros into the sand, and the piece of live rock that I placed on top has already seeded the sand with pods. My refugium looks great and is the perfect addition to my healthy reef tank.
Review: Great product - I like how there are small shells mixed in with this sand. I bought this to add more sand to certain areas of my 120-gallon reef tank. I do not have the cloudiness issues others seems to be having - I used a large fish net to carefully lower the sand into the tank, with all the pumps turned off.

## Questions & Answers

**Q: Will algae grow with just this product, light, and saltwater?**
A: Assuming you’re adding a heater too, yes

**Q: My sandbed is 1”. Is it okay to add this to an established tank with fish/coral?**
A: I really don't recommend it.  It will cloud the tank severely and leave a powdery covering on everything.

**Q: Will this really cycle a new tank instantly? Seems too good to be true.**
A: Nothing, I repeat nothing cycles a tank instantly

 This will help kickstart a cycle but requires an ammonia source and time.

**Q: Do you have to add anything else to tap water to make this fish safe?**
A: As long as you don’t have any live stock you can just add tap water I would personally use dechlorinated water

Pretty awesome product! I ordered 2 bags for my reef aquarium and it did just the job. It has a random assortment of little shells and stuff in it so it gives it a more natural ocean look.
