from Algone's website ...
" Algone is based on a biological process, during which naturally present microorganisms contained in Algone use available nitrogen compounds as a source of nutrition. The result of this nutrient uptake is micro-bacterial protein enabling Algone to retain the nitrogenous waste while eliminating the re-release into the aquatic environment.
Algone enhances the conditions of nitrifying bacteria, by creating a higher dissolved oxygen content (resulting from the conversion of ammonia, nitrite and nitrate to protein) and making a carbon source readily available as additional nutrition for nitrifying bacteria.
Algone also has a inhibitory effect on hydrogen sulfite (a result of failing filtration and high nutrient levels) which is highly toxic to fish.
Ammonia, nitrite and especially nitrate, are constantly being produced. Nitrifying bacteria need oxygen -which is in ample supply in the aquarium- to convert ammonia to nitrite and finally to nitrate. The conversion of nitrate (denitrification) requires an absence of oxygen. Aquariums usually do not provide enough oxygen free areas for the establishment of denitrifying bacteria. The flow of the nitrates to these areas is even less common. Water flow will further restrict these rare settlements due to the increased distribution of oxygen."
Micro-Bacterial Protein ? Similar benefits to an algae scrubber, but without the extra hardware and mess ? Sounds interesting ... IF it actually works.
