If you have never been to the Coral Shop and met Mike you owe it to yourself to take the drive over. Mike has some of the coolest and most colorful coral I have ever seen. His place was easy to find, Mike was very friendly and then when I got home and started putting things in my tank I found that he gave me a freebie without even saying anything. I found mikes coral to be a good valve, the coral looks great under my leds, and if you have any problems mike is there to help and stands behind his product. I believe if you drop by the Coral Shop you will be glad you did,,,,, Yellow Submarine
