I bought a 60g cube and it came with wet live sand (kept in 6inch water) The guy told me to use it as it has beneficial bacteria. Turns out, the tank has been stagnant for 2-3 weeks (no flow). Are the bacteria dead already? The sand and water were brown . I added saltwater and started cycling.....and today I stirred up all the sand. Did I just ruin a perfectly fine sanded ??
