For those of you who dont know I just upgraded in size from 5.5 to 10 gal and I was wondering what you would recommend other then MH for that size I only plan on keeping some polyps so easier to care for mushrooms and my new carribean ricodea and evently I will be adding a pair of clowns? I have on there the light that I took off my 5.5 which was a 18 watt coral life with the atinic and a 10k in it I was wondering if I was to get another of the same fixture would that be sufficent for what I am planning on doing? thanks for the help one and all
