at the moment i would not use other T5s than the ones from the brand ATI. if you ever compared it to other fixtures with the same wattage, youll be estonished about the difference... optimized reflectors, optimized chilling, etc...
i would get those sponge and ceramics out of the filter... other than that, your tank looks like a killer start... i think yous hould go that psychodelic way... with sick colored zoos and rics :D
i like that angler too
