I have the 24inch Reef capable with built in timer on a 29gal. I also have been out of the aquarium game for many years. Basically i wanted to go cheap but something decent and i didnt do a lot of home work. I will say i have successfully kept different zoa's, 4 dif acans, couple types of favia's , couple blasto's and alveopora. I had a Bubble tip but all it ever wanted to do was hide under rocks away from the light. I gave BTA away. My zoas dont always seem happy and i find myself moving them all the time. None like to be directly under the light. I find myself moving the light fixture back in forth over the tank whenever i walk by. Guess what im trying to say is that the light works and keeps my LPS and Zoas going. But i do not like the color, tends to orange out most colors in my corals except for the greens. And a very "windex" blue without the whites. I regret not doing more research and not spending on a better fixture. Once you start buying corals and noticing they dont look like they did when you purchased them you will regret going cheap.
