thanks sissy I've been looking overflow drainage up online and it may be a good idea to rig some sort of screen up or larger rocks with smaller pebbles in the drain itself so my fish dont think about visiting "dry land". Granted I have a foot and a half yet before the water would get to over flow...just dont want to take any chances since I dont have all of my rocks yet. Darn rain anyhow we've been having has made me accelerate what needs to get done! I dont know how but I bet I have 20 earth worms at the bottom of the pond...sure wish I could put my fish in there cuz they would love them!
