It rained buckets the day before. It was a full moon the day we went to the Lagoon. Maybe this impacted the less than overwhelming luminescent. If the photographer takes your photo, it will appear a little luminescent, but to the naked eye, you are basically not seeing a darn thing. I would have thought the boat would have made luminescence, but it did not. Also it took the arm movement and great photo to show what you see in these pictures. It was NOT what I thought it would be. The muck under your feet is horrifying, lol but that is the environment for this awesome to grow (salt/fresh water mix). Again, great it's cheap for a trip, but pretty underwhelming.
