i would put the sand first and then put the water.btw, how do u know until the sand is clean and ready to use? does the saltiness of the sand affect the fish?
oh, so pfs can be found in lfs huh? what if i put real beach sand in the tank, which is sand tht i can get by my own and not buying one? is it okay?
oh, really? so if i were to use beach sand, what do i have to do before putting it in the tank? just wash it thoroughly?
