Thanks for your all respond
for my heat issue, I am using 4 fans over the main tank. During a hot temp day, my acro lost tisseu badly and they were barely made it. and the other day, I found aqua medic T-5 fixture and I never try only T-5 lighting system. Now I am borrowing current
lighting system from my friend, so I have to get light fixture in the future anyway. so if choose T-5 what is a heat issue? If it is not improve then I can keep my friend's one or use my 250w MH back to the tank.
Thanks again
