Does anyone know of a source for T-8 electronic ballasts for 2 30" watt bulbs or 2 15 watt bulbs? Mine are getting old and it seems that Coralife no longer makes them. Furthermore, the fella who answered the customer service line at That Fish Place told me that the only T-8 bulbs which are made now are 15 watt bulbs. Have 30 watt T-8 fallen out of favor that much? TIA, mt
