I want to add 3" of sand to an existing mature tank
Ok, I have toyed around with it, and have made the decision that I want to add 3" more sand to my now 3" sand bed. I have done minimal searching for the ups and downs to doing this, and just want to know if you were going to do this, how would you do it...I am going to prolly use silica sand, because you can't find SD, OC, or YR down here, and I am not going to spend $2 a lb for dry sand...
So, my dilema is this, I have a few hermits and a serpent star. The other snails stay out of the sand except for one Nassarius Snail which stays in the sand... How would I go about putting 120 lbs of sand in there now?
