main active ingredients explained.
Sodium thiosulfate (Na2S2O3) Dechlorination with commercial products – Most commercially available dechlorinator solutions contain sodium thiosulfate (Na2S2O3) and convert Cl2 and HOCl to harmless sodium tetrathionate (Na2S4O6) and sodium chloride.

2 Na2S2O3 + Cl2 ? Na2S4O6 + 2 NaCl    2Na2S2O3 + HOCl ? Na2S4O6 + NaCl + NaOHSome dechlorinators use sodium bisulfite (NaHSO3) or sodium sulfite (Na2SO3) instead. NaHSO3 + HOCl ? NaHSO4 + HCl Na2SO3 + HOCl ? Na2SO4 + HCl

Since these reactions occur instantly, the dechlorinator need not be mixed with tap water prior to adding it to the tank. It can be introduced as the replacement water is being added.
One very important note should be made if chloramines are present. Sodium thiosulfate will neutralize the chlorine portion of chloramine. However, the free ammonia that is released in this reaction gives rise to an obvious problem since ammonia in small amounts is toxic to aquarium life. It would be far better to use products that specifically claim to safely remove chloramines.

Na2S2O3 + 4NH2Cl + 5H2O ? Na2SO4 + 2H+ + 4HCl + 4NH3

Sodium metabisulfite Na2S2O5
dose the same as Sodium thiosulfate but acts as preservative to neutralise last 10ppm chlorine, and transform small amounts off ammonia to ammonium making safe for aquarium.

Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA)
PolyDADMAC is used as a coagulant in 
water purification. It is effective in coagulating and flocculating inorganic and organic particles such as silt, clay, algae, bacteria and viruses. At high concentrations the organic polymer can remove natural organic matter such as humic and fulvic acids resulting in fewer disinfection byproduct precursors and less color

All our products are made to safe standards for use for human and animals thresholds
