The most significant advantage of fishless cycling is that it can reduce fish loss due to ammonia and nitrite spikes. Fish loss can be very discouraging for beginners of fish keeping, so indirectly, fishless cycling can also help beginners get a good start. Cycling aquariums using feeder fish is risky, because it infects the aquarium with any ...
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]
A build-up of ammonia in the fish tank leads to ammonia poisoning. Species of ammonia-oxidizing bacteria (AOB) can break down the ammonia and convert it to other, less toxic, nitrogen products. Two examples of AOB are Nitrosospira and Nitrosomonas. [2] The amount of ammonia present is usually accompanied by a rise in pH. As ammonia is a base ...
Modern algae scrubber designs use upflowing air bubbles to generate turbulence; when illumination is added, algae grows inside the unit and consumes nutrients. Commercial floating surface algae scrubber uses red LED lights and up-flowing air bubbles to cause algae to grow in the growth compartment.

Protein skimming removes certain organic compounds, including proteins and amino acids found in food particles and fish waste, by using the polarity of the protein itself. . Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air–water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt ...
