Do sun blockers choke the coral reef?

We were curious about the relation between sun blockers and the coral reef. How much sun blocker gets into the reef? How much harm does that do? Or does it not?
So, we dived in. Watch and see what we calculated.

And having seen that, what can you do?

Protect yourself from the sun by taking simple measures. Protect the reef by avoiding harmful chemicals, especially Oxybenzone. And as you can see, this also goes for marine life other than the coral reefs!

And use your consumer power.

Perhaps these brands look nice, but please avoid them because they are toxic for marine life
Use brands like these instead of the ones that harm marine life
