Hello fellow reefers!! I will be upgrading from a 75 gallon to an 180 72x24x24. On my 75 I'm running an ati 48" 6 bulb fixture. I love my t5s but would a 48" work on a 72" would it be sufficient or should I get a 60" 8 bulb t5. I didnt have plans to get a tank this big lol couldn't pass up the deal. Was going to do a nsa aquascape but was thinking about doing a 4.5 to 5 foot aquacape because of the fixture but the ends would be dark not very lit. Maybe low light corals on both ends. Not sure how a 4ft fixture would look on a 6ft tank... Thanks in advance!!
