urchins cause trouble in nanos imo...knock rocks/corals over, take up too much valuable space. id just take a scraper to the algae and call it good. ditch that stock skimmer too can never get those dialed in right...tunze 9002 with low pro cup works tits or a hydor nano skim that works pretty good on my 30g. also dont sweat the t5 retro there are a lot of write ups online to explain or bring the hood and materials down here and a we'll get it done.
