Colombo Nitrate Test Kit (NO3), is produced from the breakdown of nitrite in the filter.
Nitrate is relatively harmless to freshwater fish, but its presence can indicate a deterioration in the aquarium environment, and high nitrate will encourage algal growth.
The only way to know what the nitrate level is, is by testing it with a Nitrate test kit.
Colombo Nitrate Test Kit contains 40 tests.
The Comline® DOC Skimmer 9004 DC is designed for use in seawater from 60 to 300 liters (15 to 79 Gal). It operates according to the TUNZE® flash skimming principle and acquires the water through an efficient surface suction with a surface film removal, and can therefore also be used as a "stand-alone" solution in the aquarium. The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter of between .1 and .3 mm (.004 - .012 in.) and is especially quiet during operation.
The Comline® DOC Skimmer with a magnet holder for glass up to a thickness of 12 mm (1/2") is supplied installation-ready.
Air flow regulation and silencer
for an exceptionally quiet
Simple, quiet and effective - these are the current demands towards aquarium components. That is precisely what distinguishes the small Comline® DOC Skimmer 9001 DC - a true "plug and play" skimmer for small seawater aquariums with 20 to 146 liters (5.3 to 37 USgal.). There is no complicated setting or regular adjustment required for the operation. A simple installation into a corner of the aquarium is sufficient and it will work autonomously.
