Yea, but I think what the final verdict (T5 vs MH) is just personal preference. With the smaller MH fixtures, like my 20" Sunpod, it was cheaper than to get the T5 equivalent. Peef's already got a chiller from his 24 tank, so I would try to beef that tank up on MHs. Again, just personal preference I guess.
And the PCs were also really hot like you said PerfectDark. My tank actually ran hotter with the PCs and stock hood on than it does now.
