I would have thought so too. There is probably an explanation for this. First, which PAR meter and sensor are you using? You might need to use a correction factor for it. Even though Aquatic Life are not PAR monsters like ATI, I would have expected at least twice that much.
Keep in mind that the T5s will have output below and above what your PAR meter can read that is beneficial to SPS. ...so there is more there than what you are reading.
