Adsorption refers to the formation of dissolved solid, liquid or gas molecules on the surface. Adsorption is helpful in cleaning an aquarium because it allows dirt and waste to gather in one area for easy collection and later disposal. Thus, many filtration systems for aquariums have a filter media that utilizes the power of adsorption to keep the fish tank free of dirt and waste.
The Brightwell Aquatics Extrax Phos Adsorption Media from Pet Store uses silicate and phosphate, which are two very adsorbent materials. The combination of these two compounds gives very fast results that no other media can produce. Thus, it makes sense to go for this brand over others.
This media comes in the shape of a sphere and has a high porosity level, two characteristics that give the biggest reactive area. Compared to other non-spherical shaped media, the Brightwell Aquatics Extrax Phos Adsorption Media has a high and fast efficiency and reactivity level.
Take note that the silicate and phosphate or any other soluble compounds already collected are never released back to the aquarium, even when the media is already exhausted. Thus, it is safe to use in both saltwater and freshwater aquariums. It can also be used in reef systems.
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 when exhausted.
Safe for use in all freshwater and marine aquaria, including freshwater planted systems and reef systems.
