Helping divers make informed decisions about training, gear, skills, and safety at every stage of their journey.

Reef-Safe Products, Conservation &
Responsible Dive Travel

As divers, we’re guests in fragile marine environments, and our choices matter. From the sunscreen and defog we use to how we behave underwater, every decision has an impact. This guide covers practical, realistic steps you can take to reduce your footprint and travel more responsibly as a diver.


I've come up with my own personal Responsible Diver Code of Conduct so I can articulate what I believe and how I try to behave.


Reef-Safe Sunscreen Isn’t Optional

Many popular sunscreens contain chemicals like oxybenzone and octinoxate that contribute to coral bleaching and marine toxicity, even in small amounts. Choosing a reef-safe option helps protect the underwater ecosystems we travel to see.

What to Avoid:

What to Look For:

What I Use:
I carry Stream2Sea, which meets reef-safe standards, but I mostly rely on sun shirts with hoods and wide-brimmed hats. Sunscreen should be the backup, not the primary plan.

If you’re unsure what’s truly reef-safe, look for “Protect Land + Sea Certified” on the label.


Eco-Friendly Mask Defog Options

Most store-bought defogs contain surfactants or preservatives that aren’t great for coral reefs, especially at busy sites where dozens or hundreds of divers enter daily.

Better Alternatives:

If you’ve already switched to reef-safe sunscreen, changing your defog is one of the easiest upgrades you can make.


Don’t Touch, Don’t Chase, Don’t Feed

Let’s be blunt: stop touching, poking, chasing, or feeding marine life.

I never purposely touch marine life and I avoid dive ops that encourage it. It physically angers me when I see people poking or grabbing animals just to get a closer photo. I understand the context of shark feeding operations, but I still believe most marine life should be left entirely alone.

Reduce Waste on Every Trip (Thoughtfully)

Waste reduction on dive trips isn’t just about eliminating plastic, it’s about being intentional with what you bring and how you use it.

When it comes to plastic cutlery or straws, it’s not always simple:

Properly disposed single-use plastic may have less impact than poorly maintained or improperly washed reusables.

If you go reusable, be sure you can wash and dry them properly during your trip.

The issue isn’t plastic itself, it’s how we use and discard it. Responsible disposal matters more than rigid rules.


Choose Dive Operators That Protect the Dive Environment

Not every dive shop prioritizes sustainability, but some go above and beyond:

You can also look for dive centers that support local conservation or coral restoration efforts. Some operators offer tours or volunteer days where you can assist in replanting coral fragments or maintaining underwater nurseries. These programs are often supported by marine parks or NGOs and give divers a way to contribute directly.

I haven’t specifically chosen dive operators based on their eco-practices in the past, but I know I can do better. This is something I’m trying to figure out how to actually do for future trips.

Common Diver Mistakes That Harm the Dive Environment

Some behaviors are so common that they’ve become “normal,” but they still harm marine life or degrade dive sites.

The marine environment isn’t a petting zoo. It’s a shared space so act like a respectful visitor.


Frequently Asked Questions

“Reef-safe” isn’t a regulated term, so manufacturers can use it freely. Look for products with non-nano zinc oxide and avoid oxybenzone, octinoxate, and other harmful ingredients. The best option is sunscreen certified by “Protect Land + Sea.”

No. Despite the popularity, baby shampoo contains surfactants and preservatives that are not biodegradable or reef-friendly. Switch to a tested reef-safe mask defog or just use spit if it works for you.

If you’re showering, rinsing gear, or doing laundry near the shoreline, then yes...it helps. Reef-safe soaps and shampoos break down more easily and reduce chemical runoff into sensitive marine areas.

Yes. Even a light touch can damage the delicate surface of corals or introduce harmful bacteria. Coral is alive. It’s not a rock, and it doesn’t “bounce back.”

Look for shops that limit group size, use mooring buoys, avoid fish feeding, and educate guests about marine life. Ask them how they protect the reef. If they can’t answer that clearly, consider another operator.
