Thanks, I hear yeah... It's a 8x54 fixture & changing 4 out of 8 I didn't think it would be that much a hit. It was 14" around round in size.. It is now about the size of a baseball... That's what concerns me.. I can't get at it unless I tear apart my aquascape & my wonderful female clown bites the HELL of of me! Especially messing with one of her anemones.. She is such a witch!
