Which T5 should I get

[i have crabs]

no, not aimed at anyone, personally i like the good stuff and have often payed more for a similar product just cause its cooler(to someone i guess) i like to have a nice looking fixture even if its hidden in a canopy,, like my $600 reddragon return pump im quite shure is just a pump with a fluvalfx5 impeller and i nice housing ohwell its cooler shure ill pay $500 more than a mag pump. not quite shure what part of my brain turns off when i look at aquarium equipment
