The problem is that they usually have the ballast connected to the fixture. This is heavy, big and ugly if you ask me. If you are going to use them for a coral grow-out tank then fine. I just would not use them for a display tank as I feel they are an eyesore. That is just my opinion though.
No they sell just the ballast, I plan on building my own hood with reflector and ballast will be mounted under stand as how are my vho ballast right now. the reason I asked is. fish store ballast $100++++ lowes ballast $25 bucks get the point, and I know ya get what you pay for but there is not one single one of us here that thinks these fish supply stores are not ripping us off so i will chance it and fill you guys in on progress when it happens.
