trust you about what? i asked this question before i think, but i lost the topic....hehe sorry. ok so 200 more pounds of southdown, and 1/2 inch would be how many pounds...i dont have any other friends who have salt water tanks...the guy at the lfs is selling me bags of live sand. and i also dont have the money right now for 200 pounds of live rock. i want to start with some, but i dont know how much i can afford right now. (im only 18)
