Depends on the tank size , with 4-65 watt light [260 watt fixture] I`m assuming you either have a 55 or 75 gallon tank ? Also what kind of light . Odyysea fixtures have crappy bulbs and don`t put out as good as other lights .
You can keep a BTA , I have a LTA under the same lighting for a few years now and going good . But supposedly LTAs need more lighting than pc .
