## 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: Worth it, will buy more in the future. - 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.

## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice sand
*by D***A on May 5, 2013*

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.

### ⭐⭐⭐⭐⭐ Worth it, will buy more in the future.
*by G***T on May 11, 2020*

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.

### ⭐⭐⭐⭐⭐ Original bag inside another bag, no hole, though
*by S***H on January 9, 2019*

Mine arrived in the original bag, inside of another bag. There was no hole or any damage to the original bag. It was still plenty "wet" and appeared to be exactly what I thought I'd get. It was 8.55 lbs of small shell pieces and fine sand. It in finer than the CaribSea aragonite pink sand that I previously had, but settled in less than 12 hours. Make sure to actually open the bag before you decide it's dried out. The liquid is hard to see near the top of the bag. You'll notice it more near the bottom. For the price, it's a good deal. I can't speak for instant cycling ability, yet, because I plan to do tests this evening after placing it in the tank last night.
