Hello Folks... I got a problem with the drainage from my AC outside. I am growing a swamp and have standing water on two sides of this system. I started digging a hole to make a drain system and want to ask about the rock I need. After digging my hole to a dimension of 3'X 4' and 1' deep I figure to put some rock down, then my drainage pipe and then landscape fabric to protect the system from the dirt.

The rock I got is called marble chip. I got several bags, enough to get around 6" deep. I looked at the other rock that Lowe's has and the marble chips were the lowest priced rock they had. Does it really make any difference if I use the marble chips verses using another type rock for my drainage? If you can answer I really would appreciate it. Blessings. Kevin
