MarinePure PODs

• Equivalent to 5,000+ bio-balls per POD – CerMedia's own comparison figure for the surface area a single POD carries.
• Published bioload ratings – CerMedia rates the 3-pack to 100 US gallons and the 24-pack to 750 US gallons.
• Resists clogging – the rigid ceramic structure holds its shape, so flow through the media stays consistent between cleans.
• Reusable – rinse in tank water at a water change rather than replacing on a schedule.
• Sits loose or bagged – large enough to sit directly in a sump compartment, or contained in a MarinePure Mesh Bag for easy handling.

Both packs use the same POD, so there's no difference in performance per piece – only in how much total surface area you're buying. Split the difference by buying more 3-packs if 100-gallon increments suit your sump better than committing to a full 24-pack.

• Suitable for: sump compartments, canister filters and media racks in freshwater or marine systems, including reef tanks.
• Not suitable for: tight hang-on-back baskets built for loose pellets – MarinePure GEMS suits those spaces better than a full-size POD. Not a mechanical or chemical media – it won't polish water or remove odours on its own.

Rinse PODs in tank water or dechlorinated water at a water change – never under tap water straight from the mains, since chlorine and chloramine will knock back the bacterial colony. There's no fixed replacement interval; the ceramic doesn't wear out, so PODs keep working until they're due for a clean.

• MarinePure Mesh Bag (Medium) – contains a 3-pack for easy lift-out and rinsing.
• An ammonia and nitrite test kit – confirm the media is cycled before stocking up.

MarinePure PODs have no stated wear-out life from CerMedia – they're ceramic, not a consumable cartridge – and any manufacturing fault is covered by your rights under Australian Consumer Law in addition to any retailer or manufacturer terms. Standard parcel freight applies; the 24-pack is heavier and may attract a higher freight quote at checkout, though it ships as standard parcel post.

Do I need a mesh bag for PODs?

Not necessarily – PODs are large enough to sit loose in a sump compartment or media rack. A Mesh Bag makes them easier to lift out for a rinse, but isn't required for them to work.

Can I mix POD pack sizes to reach a specific bioload target?

Yes – CerMedia's bioload ratings scale with the number of PODs, so combining a 3-pack and a 24-pack, or buying multiple 3-packs, is a valid way to size up gradually.

Are PODs reef safe?

Yes, the ceramic is inert and safe for reef and marine systems as well as freshwater.

Do I need to cycle a filter before adding livestock?

Yes. Any new biomedia needs time for bacteria to colonise the ceramic before it's doing useful biological work. Run it on established tank water, or fishless-cycle with an ammonia source, before stocking up.
