what kind of lighting do i need for my 55gal, i have fish but i have a kenya green coral tree frag, and want to get bubble anemones and others plus LPS, corals?
T-5's should be fine. Get a fixture with individual reflectors (they minimize restrike between the tubes) and go with a fixture that you can control half the lights on one timer and half on another timer. This way you can use daylight and actinic lamps for a dawn/dusk effect which also minimizes sudden "light scare".
Check out our Marineland Reef Capable LED fixture. Something like this will be suitable and provide more than enough light to sustain all of your desired inhabitants.
