I don't know, chillers are not cheap either. Mine was $350. You don't need the highest quality led fixture because most seahorse safe coral are low light coral: leathers, palys, zoas, mushrooms and polyps. The exception is photosynthetic gorgs.That going to be my biggest issue. Its sitting in my living room in a corner with my couch next to it. I can always slide the couch over a little to make room but we will see. The tank will be cycling for a while anyway so I will have plenty of time to see if I need a chiller during the cycle. Or there is always the option of going to leds might be cheaper to go chiller though.
