Fold back the flaps of plastic you created with the cut and gently lift the bag out, leaving the sand behind. Try hard not to disturb the water much. If you do get some cloudiness, remember gravity works. Turn off any powerheads for a few hours and things should settle down.
Thank you very much!
One more question... can you move LR around and re place stuff after your tank has been set up for 10 weeks? I was thinking about kind of re arranging some rock and making it look slightly different. I worry about some of the little critters like my hermit crabs and emerald crabs. I don't want to mistakenly harm one or stress my two damsels out. And of course, the most expensive thing I have: a few mushroom and polyp corals and a leather coral.
Is this possible while adding my sand??? I could even do this during a water change to help perk everything up with fresh saltwater.
