Home hardware also sells stuff under the "Weather shield" brand. It's kinda green label 35 year Silicone. Says water proof seal on it. and right on the main label is one of the only silicone's that says right on it "Aquarium safe"

Actually after writing that I decided to take a pic

Just make sure that the sand isnt to small i tryed the same thing looked good but had to do it twice as the sand was to fine the first time and it didnt cover enough redid it with bigger sand and looked sweet but turned in to the tank of death because i used the wrong stuff
