not to whore your thread, but im jumping on board also this week and pickin up a RBTA on Wednesday, my tank has been successfully going for about a year and a half now, so I think its time. I have a pair of clowns that right now are hosting in some pulsing xenia, I recently purchases a 150w MH pendant to go along with my 125w worth of PCs, so I think im ready, im interested to see how yours does. Does yours have green or white around the oral disc?
