Mar Rojo or Red Tide…We have a bit of red tide going on right now in the Gulf of Papagayo, Costa Rica. Red Tide is a natural phenomenon. It is eerily beautiful. The water was clear for most of the dive and this cloud of red tide came in. It was really reddish orange with clouds of purple. We were diving at local dive site, Los Meros in the Bahia Culebra. We found a seahorse and watched many schools of fish.
