Btw bro, are u the one who PM me for the vitron MH lights? I mean u "jio" me to get the lights together. Actually, i found out that our sponsers eaquanature are selling a good T5 tube brand. It is D-D. Try going to this website <www.d-daquariumsolutions.com>. Go and search the lighting. And read their reports. At least, will save money on electrical bill.
