Rebreather CO2 Absorbent


The Molecular Products Sofnolime and Micropore ExtendAir carbon dioxide (CO2) absorbents we sell are ONLY for use in sport and technical diving semi-closed and closed circuit rebreather systems. Because there are a great many types and formulations of carbon dioxide absorbent, it is critical to use only the specific CO2 absorbent recommended by the manufacturer of your specific model rebreather.

We are proud of the quality of our customer service, but we will NOT offer advice on CO2 absorbent selection or use other than what you find published here. If you are uncertain as to what product to purchase, we strongly recommend you seek formal training for your specific model rebreather. We do not sell CO2 absorbent for any purpose other than diving.

It is critical to follow the specific absorbent use recommendations of your rebreather manufacturer for your specific model. Use of the improper product can cause problems such as excessive work of breathing or shortened scrubber times. Recommendations from some rebreather manufacturers are:

Nargra Reef

Reef Dive Reef Dive | Boat access Boat access

Night Dive Site Open Water Rated Reef Dive Site Spearfishing Site

Depth: 3 m (9.84 ft) to 13 m (43 ft)

Level: Open Water and beyond.

Nargra Reef lies offshore from Keillers Beach Road, east of Portland, in Portland Bay (aka Henty Bay) on Victoria's Discovery Coast. It's a limestone reef that has been eroded by the swell into a series of gutters and overhangs.

Nudibranchs and gorgonian corals adorn the ledges along with a variety of fish species. The area is also noted for the fossilised Giant White Pointer Shark Characharadon Megalodon teeth that are occasionally found here.

This area is frequented by boats, so please make sure you display your dive flag in this area.

Nargra Reef is accessed by boat from the Portland Harbour, Lee Breakwater Road North Ramp or the Portland Harbour, Lee Breakwater Road South Ramp.

Best dived in good conditions with a low swell with light north or northerly winds. See WillyWeather (Portland North) as a guide for the tide times and the height of the tide.

Gunditjmara country

Traditional Owners — This dive site is in the traditional Country of the Gunditjmara people of far south-western Victoria which continues over the state border into a small part of south-east South Australia and is bordered by the Glenelg River to the west and the Wannon River in the north. This truly ancient Country extends 100 metres out to sea from low tide and also includes Deen Maar (aka Lady Julia Percy Island) where the Gunditjmara believe the spirits of their dead travel to wait to be reborn. We wish to acknowledge the Gunditjmara as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
