Much cleaner water, fewer toxins, healthier fish, less scum and less cleaning too!
Poly-Tech Super Filter is an innovative filtration pad utilizing polymeric media, ferric-oxide-hydroxide, and ionic exchangers in an
open fiber matrix to remove a very broad range of chemical waste and pollutants. Poly-Tech Super Filter’s adsorptive, ionic,
molecular sieving and mechanical properties create a captive aquatic environment of extreme purity, clarity, and low toxicity. These
filters remove major toxins including ammonia, organics, nitrates, heavy metals, medications and dyes as well as phosphates and
are designed with extremely low impact on trace elements. Poly-Tech Super Filter provides significant aid in maintaining the
pristine environment so essential for fish, live corals and live plants while minimizing the labor necessary to achieve great results.
Color changing feature and regenerative capacity
As Poly-Tech Super Filter adsorbs waste, it darkens significantly giving a visual detail of its action. The degree of discoloration
depends on the application environment and the prevailing pollutants being captured by the filter. Highly polluted tanks will show a
greater degree of discoloration. A powerful feature of the Poly-Tech Super Filters is that they can be easily regenerated using a
simple table-salt solution! Each regeneration significantly restores filter capacity. Many of the compounds such as phosphates and
very reactive organics get permanently locked within the filter so restoring the original color may not be possible.
Regeneration instructions
When filter becomes substantially discolored, first rinse well under running tap water, and then prepare regenerative brine solution
by dissolving ½ cup of table salt in ½ gallon of very warm tap water. Pour 2 cups of brine solution into a shallow pan or dish and
soak filter for a few minutes. Dip filter in and out of brine solution 5 or 6 times allowing solution to fully drain out of the filter each
time. Discard dirty solution and repeat 3 more times until the whole ½ gallon of brine is used up. Rinse filter under running tap
water and return back to service. Each regeneration restores up to 75% of filter capacity. Poly-Tech Super Filters can be
regenerated up to 6 times, and then should be replaced. For optimal performance weekly regeneration is recommended.
Suggested applications for high flow active filtration
Poly-Tech Super Filters can be cut with regular scissors and are easy to work with across many applications. In a wet-dry filter cut
to fit across the pre-filter tray or cut and place it over the top of pre-filter sponge. In hang on the back power filters cut to match the
size of filter cartridge or sponge insert. In canister filters cut to cover the entire area of the filter basket or tray. Use separate pieces
to fill the entire tray area without water bypass. Stack multiple layers instead of sponges for outstanding chemical and mechanical
filtration. In nano tanks cut to size of cartridge or sponge.
