RP Ammonia Block eradicates poisonous ammonia infinitely quicker than any other product on the market. New aquariums can be stocked immediately without the fear of an ammonia spike or losing fish. Simply add the correct number of PODS to your canister filter and allow your filter to mature naturally over the next 12 weeks.

Each pack contains three individually sealed 100 g pods, together sufficient for up to 1500 litres of water.

APPLICATION

1 POD – 0-250 Litres
2 PODs – 250-750 Litres
3 PODs – 750-1500 Litres

For use in external canister filters and some internal filters. Our PODs MUST be placed flat (not squashed up), to maximize exposure to water flow after the biological section to function correctly. When used with our Nitrate Remover, Ammonia Block must be placed before. This will ensure that you get clear and algae free water.

Remove PODs whilst using any fish disease treatment
In NEW or MATURE aquariums, it is recommended that you clean your filter before use.

Setup & Use

Rinse the pods before use. RP’s data sheet asks for it and
it takes ten seconds.

How many pods:

• 1 pod — up to 250 litres
• 2 pods — 250 to 750 litres
• 3 pods — 750 to 1500 litres

A pack holds three pods, so one pack covers a tank of any size up to 1500
litres.

Where they go, and this is the part that matters. The pods
must sit after the biological media in the flow, and they
must lie flat and not squashed up, so water passes across
their full face rather than round the outside of a wedged lump. RP are blunt
about why the order matters: putting ammonia removal ahead of the biological stage
starves the filter bacteria of their food source. In an external canister that
means the top basket, laid flat; in some large internal filters the same rule
applies.

Running a sump instead? RP’s own instruction is to release
the resin from the pods and run it loose in a media reactor, at a flow rate
of 50 to 150 litres per hour. That is a slow-flow reactor
setting, not a full-bore one — too fast and the water does not spend
long enough in contact with the resin.

Clean the filter first. RP recommend cleaning the filter
or reactor before fitting the pods, in a new system and a mature one
alike.

Take them out during any medication. Treat these the way
you would treat carbon: an ion-exchange resin sitting in the flow will strip
the treatment you just paid for. Remove the pods for the course, then put them
back.

Running it with the Nitrate Remover? Ammonia
Block goes before it in the flow. That order is on this listing
already and it is worth repeating, because reversed it does not do what you
want.

Twelve weeks, then discard. RP rate the pods for up to 12
weeks in service and their instruction after that is simply to throw them away
— there is no recharging step, and a used pod left in the filter is at
best inert media taking up a basket.

Handling: gloves are recommended, wash your hands after
handling, and keep the granules out of your eyes — RP note they will
cause irritation, and to rinse thoroughly for several minutes if that
happens.

Specifications

• Form — round mesh pods. RP describe the contents as
  grey-green granules with no odour.
• Pod weight — 100 g each.
• Pack contents — three individually sealed pods,
  together rated for up to 1500 litres.
• Chemistry — an ion-exchange resin selective for ammonia. RP’s hazard
  classification line on the data sheet is simply “CONTAINS ION EXCHANGE
  RESIN”.
• Removes — ammonia, in fresh and salt water.
• Service life — up to 12 weeks, then discard. Not
  rechargeable.
• Sump / reactor use — resin can be released from the
  pods and run loose in a reactor at 50–150 lph.
• Compatibility — can be run alongside any other RP
  Aquatics product.
• Storage — well-ventilated place, and not above
  50 °C. That second figure matters in an Indian summer: a sealed
  storeroom or a car boot will exceed it.
• Classification — RP’s data sheet records the
  product as not hazardous or dangerous, not harmful to plant or animal life,
  and not harmful to the environment. Ingestion is stated as unlikely to pose a
  health risk; eye contact will irritate.
• Made by — Resin Products Limited, United
  Kingdom.

One thing we cannot resolve from RP’s published material:
their data sheet for this product is headed “Ammonia Block/Marine”, which reads as
though a separate marine formulation exists, while their consumer page sells a
single product and our listing says it suits tropical, coldwater and marine
alike. We have not changed that claim, but if you are buying for a reef system
and the distinction matters, ask us and we will put it to the supplier rather
than guess from a slash in a document title.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.
