Independent Testing


AllClear's team investigated a wide range of established water-testing programmes to establish what may be suitable for fish. AllClear's team could see that the available, standard programmes were fine for testing drinking water for people, but they soon found that these programmes were unsuitable for testing water treatments for fish.

Fish and people are different and have different water needs
(see library section).


E.g. Allowable amounts of chlorine, chloramine and copper etc., in renal dialysis water, are fine for us but are too high for many ornamental fish, for their long-term good health.

The following testing programme criteria for 'fish' were established with the assistance of scientists of good standing.


  • Independent testing undertaken at a U.K. Water Company's NAMAS accredited laboratory. (A selection of AllClear's independent test results are opened to public view, on AllClear show stands and at public talks undertaken by AllClear personnel.)

  • Testing was based on U.K. and E.U. maximums for mains tapwater for various substances.

  • Test water was measured in Imperial (U.K.) gallons, which are larger than U.S. gallons. (Multiply U.K. gallon values by 1.2 to establish the equivalent U.S. gallon value.)

  • Testing was undertaken on tap water at its normal ambient temperature. (This coldwater testing is more demanding on most purification media.)

  • For the disinfectant group testing criteria were based on the more difficult reduction of total chlorine including chloramine (more demanding than just free chlorine testing).

  • Total chlorine (free chlorine and chloramine) ranged from 0.59 - 0.84 mg/l, average 0.71 mg/l.

  • Influent chloramine ranged from 0.39 - 0.44 mg/l, average 0.41 mg/l.

  • Pesticide testing was based on influent atrazine at 5 ug/l. Atrazine is generally seen as the hardest of the pesticide group to reduce, it was the ideal testing substance to determine pesticide reduction performance. (The pesticide group includes algicides, fungicides, herbicides, insecticides, molluscicides etc., and pesticides themselves.)

  • Metals testing was based on dissolved toxic metals. Apart from iron particles (iron oxides, hydroxides and carbonates) in hard water, it is the dissolved toxic metals, which are generally more harmful to fish.

  • Dissolved toxic metals were tested at influents of 100 ug/l and 200 ug/l.
