Ditch the T5s unit and add some MH?

[the marine apprentice]

hey martin. id stick with the t5 set up or maybe upgrade to a six bulb. im running t5s on my nano and will never go back to mh on it. i also have a 250 watt mh setup on the hex tank which is 24 deep and it works well also. but i just hate the heat that it puts off. get a good selection of bulbs in there and i am sure your sps will be growing soon enough. mine dont grow as fast as id like them to but i am happy with the way they look and the way they are growing.
