Nitrates : Nitrates occur in water as the end product in the biological breakdown of organic nitrogen, being produced through the oxidation of ammonia . ammonia every other day when the aquarium is first set up, and once a week after the biological filter has been established (in about 4 - 6 weeks). Testing Tips 3This salicylate-based ammonia test kit reads the total ammonia level in parts per million (ppm) which are equivalent to milligrams per liter (mg/L) from 0 - 8.0 ppm (mg/L).

When I realized the levels were high I added Stress Zyme. But, that didn’t help and no matter how many water changes I do the Ammonia stays at 4 ppm. Ammonia 4 ppm accuracy Gas Detector -10(-40)+40 degree NH3 Mar.10 Relay Package With the NH3 relay package two potential-free contacts are available for the connection to external devices. The switching thresholds of these relays are selectable via potentiometer in the range of 10 - 90% of NH3 concentration.

Ammonia (NH3) is a colourless gas with a distinctly pungent odour at normal atmospheric temperatures and pressures. The odour threshold is approximately 5 ppm.

Convert ppm to percent. 1% = 1/100 1ppm = 1/1000000 So 1ppm = 0.0001% So to convert from ppm to percent, divide the ppm by 10000: x(%) = x(ppm) / 10000 Ammonia–Ammonium Equilibrium Ammonium in the soil solution can be considered as a weak acid in equilibrium with its dissociation products NH 3 and H + as follows: NH 4 + = NH 3 + H + pKa = 9.25 The pKa value indicates the pH at which half of the ammoniacal N is NH 4 + and half is NH 3.
