Spherical Phosphate Adsorption Media for Use in All Freshwater & Marine Aquaria.Overview:- Advanced adsorbent of phosphate and silicate; provides rapid results.
- May be used on an on-going basis as part of a sensible nutrient-control program.
- Spherical
shape and porosity maximize reactive surface area; promotes reactivity
and efficiency by maximizing contact time and minimizing tendency to
pack and channel water, and outperforms competing non-spherical
phosphate-adsorbent media.
- Recommended usage is 2 g of Extrax
Phos per 1 US-gallon (3.8 L) in aquarium; 600 grams will adsorb up to 20
mg/L phosphate in 300 US-gallons (1,136 L).
- Does not release phosphate, silicate, or soluble compounds into aquarium system .
- Safe for use in all freshwater and marine aquaria, including freshwater planted systems and reef systems.
Technical Background:Phosphate,
while required in miniscule amounts by living organisms for proper
functioning, can indirectly negatively impact the overall appearance of
an aquarium system if it is allowed to exist at a concentration
measurable by most aquarium test kits (e.g. >0.05 ppm); in order for
this impact to occur, other undesirable substances must be present in
varying concentrations, however these substances are rarely limiting in
the typical marine aquarium. Because of this, elevated phosphate
concentrations, whether sporadic or chronic, should be combated. The
combined characteristics of shape, porosity, and grade of material
enable Extrax Phos to effectively trap phosphate and remove it from
aquarium water. This method of treatment may be used as needed and/or on
a continual basis to maintain an immeasurable phosphate concentration
in a marine aquarium.
While
Extrax Phos provides a workable solution to potential phosphate-related
problems, it should not be seen as an alternative to proper and
sensible aquarium husbandry. Aquaria with extremely-low to immeasurable
reactive phosphate often appear more pristine than those in which
phosphate is allowed to persist in an elevated concentration. Feeding
aquarium inhabitants sensibly, limiting the use of organic-based
supplements and additives, use of a high-quality synthetic aquarium salt
blend, and performing water changes/replacing evaporation with purified
water are all important aspects of phosphate control. Additional means
of limiting phosphate are maintaining a culture of macroalgae in the
system to naturally deplete phosphate and other substances, and/or the
use of an effective and well-maintained protein skimmer.
Instructions and Guidelines:Prior
to first use, rinse each 600 grams of Extrax Phos in ½ US-gallon of
purified water, then discard water; note that Extrax Phos material may
become hot when first immersed in this water. Use 2 grams of Extrax Phos
per 1 US-gallon of water in system and monitor phosphate concentration
(“[PO43-]”) during usage.
Apply
Extrax Phos media as required to obtain and then maintain an
immeasurable [PO43-]. It is time to replace Extrax Phos once the [PO43-]
in the system either ceases to decrease (e.g. when the [PO43-] is
>0.05 mg/L and is no longer falling) or begins to increase; this
indicates complete media exhaustion. Slight changes in coloration of the
media with usage do not necessarily indicate exhaustion and should not
be used as a guideline for when to replace the media.
The
longevity of Extrax Phos is largely dependant upon the pre-existing
phosphate concentration in the aquarium; the higher the initial
concentration, the faster the material exhausts. Effectiveness of Extrax
Phos is largely related to the reaction time it has with aquarium
water; the longer the reaction time, the more effectively it will remove
phosphate and silicate. In all cases, the use of a mechanical
pre-filter to remove particulate organic material from water prior to
its interaction with this media will inhibit biofouling and prolong
effectiveness. Due to the friable nature of the material, use in a
fluidized-bed filter is not recommended; instead, placement in a
canister filter (active filtration) or 150 μm mesh filter bag (passive
filtration) are recommended. If choosing the latter approach, place bag
in an area of medium-flow and turn bag over once during usage to shift
the media and increase filtration effectiveness.
