I got to get
rock for my 120g and buying aquarium rock could take you broke, but
we wanted white & baby blue, if I could find white I could just add a

After your 120 with the baby blue and white fully cycles the bacteria
deposits and detritus on your white and baby blue may make it look
like baby pooed.
