This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and... more

Natural sea water Contains about 10 mg/L as silicate. In reef or other marine ... Natural sea water Contains about 10 mg/L as silicate. In reef or other marine aquaria silicate should be 1 mg/L or less. Silicate is non-toxic to �sh and invertebrates but is ideally kept below 1 mg/L to minimize diatomaceous algae. In freshwater... more
