I am new here. I looking for T5HO for a 30 gal. 30x16x10. The bulbs can be 30, I found the hard way they don't make 30 in ATI, Gieseman. I can't hung the light for ceiling, I don't care if the lights over the hang the tank. I am 73 and suffer from a stroke, and I my mind has a very hard time under stand. Thanks Ed
