## Overview

AQUANATURAL Oolitic Aragonite Aquarium Sand is a premium, sustainably harvested substrate from The Bahamas, designed to stabilize pH at 8.2 naturally. Its pure calcium carbonate composition and ideal grain size create an optimal environment for marine and reef tanks by supporting beneficial bacteria and maintaining crystal-clear water.

## Description

Product Description Bahamian Aragonite Aquarium Sand is the ideal substrate for marine, reef or African Cichlid aquariums. It is a pure Oolitic Aragonite sand collected from the crystal clear oceans of The Bahamas, with no harmful tar, organics or impurities. This aquarium sand has unsurpassed buffering capability and helps maintain a natural pH balance of 8.2 without the constant addition of chemicals. One kg of Oolitic Aragonite Aquarium Sand offers over 1 million sq. cm of surface area providing a huge space for housing ammonia, nitrate and nitrite reducing bacteria. Oolitic Aragonite Sand is the ideal grain size for reef tanks, fish tanks, plenum systems and refugiums. Directions Rinse and place in base of tank. Cloudiness is a natural side effect of calcium carbonate and will be removed by filtration resulting in super clear water. Filters may need to be cleaned more frequently the first few hours/days after adding.

Review: Great substrate for creating sand bed in reef tank - Wonderful substrate for marine tank. Some small grains are so round and perfect. Definitely needs a good wash before adding to the tank as lots of dust comes out.
Review: Worth it! - Takes some time to rinse but once in and settled it is gorgeous to look at plus water parameters are stable.

- 98% pure calcium carbonate - no impurities like other sands

## Questions & Answers

**Q: Can you use it in a fresh water tank?**
A: Yes, it instructs to rinse it first which would be wise. I didn't follow that step and had a very cloudy tank for the first week while it cycled.

**Q: I got diamong goby,will this sand avoid cloudiness with diamong gpby ?**
A: I have not tried it yet but the review says the sand clears up soon

**Q: I was going to add crushed coral to my 5 gallon tank for my nerite snails. will coarse aragonite be the same?**
A: This is a fine sand that's actually coral that's super crushed.  It adds to snail shell hardness.  I have a few Nerite and Apple Snails happily living with it, and it cleared up all of the old "soft water" shell weakness.

**Q: Is this enough sand for a 5 gal tank?**
A: That depends how thick you like your substrate. Personally I do not go higher than 1", and i have a 1200 gal and a 650 gal. I used this sand in my sand filters (2). But for 5 gallons this should be plenty.
