An Important note for divers regarding water
Its is well known divers need to keep themselves hydrated to avoid the possibility of getting DCS or the bends when diving.
A diver is supposed to drink at least 8 glasses of water a day while diving (more in tropical climate) and this brings up an interestng point about the drinking water on the island.
The water is reverse osmosis which means its basically sea water with the salt taken out and it contains absolutely nothing, no minerals no salts no electrolites, it contains nothing.
So basically its useless for a diver who needs to rehydrate so a diver should be aware of that and take additional fluids in in the form of Gatorade or those electrolye powders you can buy from the pharmacy that can be mixed with the oscmosis water to provide you with the needed minerals salts and electolites.
