The pumping sessions lasted an hour, and the results speak for themselves. Corals absorbed 17.3 percent of the sodium hydroxide mixture on average, resulting in coral calcification (growth) increasing by seven percent. That affects shell growth and thickness in invertebrates as well. So all we need to do is start dumping sodium hydroxide across coral reefs to combat rising water acidity, right? Sadly it isn't that simple. The Verge writes that doing so would be expensive, not to mention pretty difficult in terms of logistics.

The only real way of fixing our oceans is by going back to the source of the malady -- carbon output -- and reducing it. Until then, coral reefs and sealife will almost positively continue to be damaged while more and more dead zones form and algae blooms.
