Everybody here in the forum have provided so much knowledgeable information sound judgments and advice that 'I have done been beaten down' by the sound arguments made about the nitrogen cycle and cycling aquariums. I guess I will try testing aquarium water. though I donít like runnen with my tail between my legs to a new and different view.
Always start with clean hands equipment and test area.
Oneís finger tip should never be used to seal the opening of test vial and will contaminate the sample.
Test vials should never be rinsed in the aquarium and test samples must not be returned to aquarium but be discarded.
Rinse testing vial several times in tap water to insure there is no contamination from previous test.
Discard rinse water do not return rinse water to aquarium
Use Water from the aquarium as final rinse so residual wonít affect the results.
Submerge the rinsed test vial that is capped to midwater
Open test vial and allow to fill
Cap test vial while submerged
Discard excess water do not return excess water to aquarium.
The time between collecting a sample and testing the sample may effect results
Validate sample by collecting two samples.
Use reagents before expiration date
Store reagents in a cool dark place
Liquid reagents will concentrate due to evaporation and adsorption of air into the solution altering test results.
The angle the reagent bottle is held in relation to test vial will effect the volume of each drop of reagent thus altering test results also too much reagent or too little will affect test results.
Roll capped test vial in hand do not shake up and down to mix. (Using a two magnets should work for mixing tool).
Matching test solutions to color comparator use white paper background and read into normal daylight or incandescent light source. The type of light can cause major comparison problems and different results
Exposure to sunlight will cause nitrite color samples to change color.
The color of the water can alter the color comparison. Kordon LLC - Kordon - Low Range Nitrate Test Kit http://www.fishchannel.com/fish-health/healthy-aquariums/water-testing.aspx http://aquabaz.tripod.com/aquatru.htm
