Thanks for all the kind words, I wish I went with the dementions as reefjunkies new 500g tank, my 300g just looks to small for me after one year. Oh yeah Brad mp60 are bulky but sence you will have a inwall system they won't seem all that big sence you will only see the half of it. If I were you I'd go with 4 mp60's, good investment for sure. I just wonder what your going to do for lights. :p
