You people are a bad influence ;D. My 29g reef lasted all of 3 months my Discus are getting the boot out of my 75g. It going to be my new reef!!! I like SPS corals and the one I have is growing good. I will need some strong quality water movement and I think I my buy a Wave 2K. I was wondering what you guys all thought of them. $200 is steap but it is cheaper than the Tunze.
