An economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core.... ( Read More )
The material has a high surface area and supports a high density of bacteria and although it has capacity to trap nitrate, de-nitrate™ as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic.
“Live” rocks or reef rocks remove nitrate by anaerobic denitrification. de-nitrate™ removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous de-nitrate™. As with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. Excessive flow rates should, therefore, be avoided, as they may impede development of an adequate anaerobic environment to support denitrifying bacteria.
de-nitrate™ is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter. At slow flow rates (less than 50 US gallons per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.
Dry goods are dispatched daily and can take 1 to 5 working days to arrive.
Live fish, live plants, and frozen food require 2 to 7 working days or more due to special handling requirements.
All our live stocks are thoroughly tested and quarantined before packing and guaranteed to arrive free of tapeworms or diseases.
Important to note that small tropical fish and inverts lose color during transport and will arrive pale or white, a proper environment and diet is needed to regain coloration.
Any death or illnss of live animals after being added to an aquarium cannot be replaced or refunded. If such problems are encountered then it is connected to aquarium conditions or noncompatible tank mates (e.g. mixing with fish or plants from other sources).
Fish acclimation to a new aquarium is the sole responsibility of the buyer and not the Discus.ae delivery team.
