I'm looking at upgrading from pc to t5. I have a 55 Gal w/ leathers, zoo's and some lps. Been looking at nova extreme pro, aquatic life, tek, and ati. The question is would it really be worth the extra hundred bucks or so to go with the tek or ati, I mean are they substantially better to shell out all that cash or should I just go with the cheaper nova or aquaticlife. ThAnks for any info.
