I have a 125g reef tank currently running with double Pc's now and want to install Halides so more coral species can survive. As with everything in this hobby i know the hood systems are a fortune. I am a handy person and working with my hands is my profession. What i need is a good direction to go in. A shopping list and a primative drawing would be ideal. I have been into salt water for less than a year, and i can tell you i am hooked and serious. I however enjoy my money also and don't want to spend over $1000.00 on a hood system if i don't have to.
