Review: Lovely colour - Looks really great in the tank can't wait to get fish in there
Review: Best sand on the market - I thought I made the wrong choice when the delivery came but once the water was in and the lights were on it was the best decision, beautiful white sand with small specs of Fiji Pink rocks and really helped the chemical balance within my tank, Will 10/10 recommend.

## Questions & Answers

**Q: Will 1 bag be ok for a redsea reefer 170?**
A: I started with two bags in a 250 litre tank and found I needed a third to give me roughly about 2 inches of sand depth coverage - less at the back due to powerheads shifting the sand towards the front half. 
Hope this helps.

**Q: Can this be used in freshwater tanks too?**
A: I would suggest not....it’s a marine substrate with marine bacteria which would be killed off by fresh water.....

**Q: Can this be used  for african Cichlids**
A: this is live marine sand, (sand with live marine bacteria ) for fresh water you can use ordinary marine sand, which is exactly the same as the live stuff but without the bacteria.

**Q: Does it have expired date? If i want to keep it for a few months without using it?**
A: Would imagine so, can't see it bein any problem storing it for a while though.
