ok so i have a 20g reef tank with 2 65w pc and one of my ballast just burned out. so i am debating on what kind of light to get now. i am debating on getting another pc fixture or a 2 bulb t5 or i might even get a 4 buble t5 but im not even sure if the 4 bulb t5 would be needed. the tank at the moment is a mix of softies a few acans and some sps. i did have a clam in the tank at one time but moved it to my bigger tank for space issues.
