What is nitrate?
Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (ammonia and nitrite). Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth.
What is the correct nitrate level?
The level of nitrate is dependent upon a number of factors, including the nitrate level of the tap water (or spring water etc) feeding into the pond, the number of fish and the amount of food fed. High nitrate levels will lead to algal growth. A nitrate level of zero is ideal and implies a balance between waste produced by the fish and nutrients taken up by the plant life. Remember: this plant life does include algae.
What do I do if the nitrate level is wrong?
Maintenance of a zero level of nitrate is extremely difficult. Most domestic water supplies have a low level of nitrate. The key to maintenance of low nitrates is regular water changes to dilute the build up of nitrate.
How to use?
This test kit reports concentration in terms of nitrogen (NO3-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 4.43 (NO3-N). For more information on this calculation, click here.
Q: Why do I run out of 1 reagent before the other(s)? A: We fill our test kit reagent bottles to a minimum amount before they are put through a vigorous QC regime. This means that the vast majority of bottles will in fact be overfilled by varying amounts meaning that the reagents may well run out at different rates but you should be able to carry out at least the number of tests stated on the packaging.
