what is the best way to add a new scape to an aquarium that already has sand in it? when my new aquarium was delivered and set up they went ahead and brought us water and filled the tank. i got ahead of myself and added the sand not thinking ahead about my scape.. i knew better got impatient and used poor judgement. now i am working on the scape but really do not want to remove the sand. Does anyone have any thoughts or processes they have successfully used? ty
