Kent Marine Nitrate Sponge is a granular zeolitic medium which works by two methods.
Place Nitrate Sponge in a large mesh (800 micron) bag on top of your wet-dry filter or in a canister filter, where water will flow through the material. It can be used as an excellent media in de-nitrators and other slow-flow applications, and is more efficient in this type usage (see below). Test nitrates regularly. Several weeks will be required to see an appreciable drop in nitrates. (Caution: nitrate testing is the most difficult of all aquarium tests, and many aquarium test kits are inaccurate for marine systems. We recommend that you use the SeaTestTM or FasTestTM test kit by Aquarium Systems® for accurate results!)
Considerations for use:
Nitrates are best brought down initially with large water changes with a low nitrate salt, such as Kent Sea Salt. Deionization or reverse osmosis filtration of tap water nitrates will also help if your tap water contains significant levels of nitrates. Each treatment of Nitrate Sponge will reduce nitrates by about 20 ppm (total nitrates) for the stated size. Not overfeeding the tank, good maintenance practices, regularly vacuuming of detritus, regular use of Kent Marine Reef Carbon, and regular changing of filter floss are critical to nitrate control and water changes are absolutely necessary! Products which contain gluconates, other sugars and heavy organic chemicals should be avoided since they will foster undesirable growth of cyanobacteria. Phosphates and silicates are also nutrients or fertilizers which, given proper lighting and other nutrients, will promote rapid growth of undesirable algae, diatoms and cyanobacteria also. Kent Marine Phosphate Sponge can be used simultaneously with the Nitrate Sponge to lower the levels of these fertilizers and help reduce growth of these unsightly nuisances.
If you have a bad nitrate problem, consider purchasing a filter housing in which to place the Nitrate Sponge. Fill this housing with aquarium water and let stand totally closed, with no water movement for 3 weeks. This will give the bacteria time to multiply and populate the Nitrate Sponge. Tap your main pressure line from your aquarium pump with small airline tubing and a small air valve. Adjust the valve to allow one drop per second to flow out of the filter back into your sump. This unit requires no feeding and therefore cannot produce deadly hydrogen sulfide gas as other systems might.
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.
