i think the more focused is correct. Still i definitely prefer t-5's over halide...thinking in economic gains...i see nothing beneficial from Halides over T-5's for plants (except the fact that you only need one bulb). T-5's consume less energy and get less hot
ill also be getting another 40 breeder soon, will lay right below this tank. atleast one of the t'5 units are going on the bottom and the 2nd one prob on top along with this one. Gota attach my splitter soon
need to buy bubble counter
