Im about to set up my tanc and add the SW.Im ordering my LR in 3 days ofline.Should i add sand before i put the rock in or after its cured?I only have normal output light untill chritmas so i have 3 months to cure them .
Once the tank has cycled and the critters from the LS and LR become active and your tank matures it will be OK.
A good clean up crew will help assist this process.
