Hi all. This is my first post here so bear with me. I have a 120 gallon tank and am thinking of switching out the current blue gravel to a white sand. I read a few reviews that said that the sand looks great but that it shows the fish waste alot and thus requires more frequent cleaning (some even mentioned 2-3 times a week). Does anyone have any experience with white sand and if so what are your thoughts on how often it should be cleaned in order to look nice? Also any comments regarding sand vs gravel would be appreciated as well. Thanks.
