Mchums Posted November 29, 2017 Share Posted November 29, 2017 question - i'm moving to a bit bigger tank and I have some CaribSea Arag-Alive sand that I didn't originally use and still in the bag (about 9m old). I can see through the clear parts some of the green/pink bacteria growing in there. am i better off getting new sand or I should be good? Thanks!

danlu_gt Posted November 29, 2017 Share Posted November 29, 2017 better check the expiration date! You can just treat it as dry sand.. rinse it well in bucket before use. If you're still concern about the bacteria growing in there. After you rinse it well, soak it in bleach water. Then just dechlorize before use. 1 Quote Link to comment Share on other sites More sharing options...

SantaMonica Posted December 17, 2017 Share Posted December 17, 2017 Should still be ok, if you let is aerate and settle. Quote Link to comment Share on other sites More sharing options...
Mchums Posted December 19, 2017 Author Share Posted December 19, 2017 (edited) thanks everyone. So I did go ahead and use it. BUT, before I did - i put about a cup of it in some salt water and mixed it up then let it settle. Tested for ammonia and nitrates and both were 0 which was great. used about 1.5" of sand, moved about 1/2 the water over from my old tank, topped off with new water and matured live rock. Took about a day for the fog to dissipate and the tank was good to go - it didn't even cycle. Edited December 19, 2017 by Mchums Quote Link to comment Share on other sites More sharing options...
