Use of Turf algae inside modern ATS filters (Algae Turf Scrubber)


Taking into account that there are multiple biodiversity in the reefs, in our aquariums we must try to reproduce the aforementioned biodiversity to obtain a stable and balanced tank.
Unfortunately, for reasons of space and volume, it is not possible to recreate in the aquarium all the habitats that mother nature has created in the various layers and depths of the sea. As is well known in the reefs not only corals live but a large amount of algae that are fed by the nutrients and organic load produced by the fish, as well as by the discharges deriving from human settlements.
Therefore, the ATS TURF Scrubber filter plays a fundamental role because, at least in part, it simulates the processes generated by algae present in the rocky substrates and present on the semi-emerged parts of the coral reef.
It should be noted that the algae in question grow in the form of turf, with filaments in the shape of bushes.
The aforementioned lawns are composed of numerous species of algal filaments, erect and tightened together, with limited height, which generally reach a few millimeters which allow to retain a large quantity of sediments and zooplankton.
Previous scientific studies have shown that the aforementioned ATS filter is able to assimilate considerable quantities of nitrogen and phosphorus. In 1970, Dr. Walter Adey put into practice this system of assimilation of nutrients, through the use of algae, commonly called Turf.
The development of algae within modern AT filters simulates some of the processes that occur in nature through the flow of water on special semi-submerged supports, illuminated with a specific color temperature.
Obviously, it is necessary to periodically remove the algal carpet that will form in the support (placed in the filter inside the ATS) and with them the nutrients absorbed by the aforementioned algae will be subtracted.
From information received from the American aquarists of my acquaintance it would seem that this filtration system is able to maintain adequate levels of nutrients dissolved in the tank. Infesting macro algae do not proliferate in the tank and zooplankton proliferates on the support of the ATS filter.
The lighting of the ATS filter at night is strongly recommended because by doing so it will be possible to keep the oxygen percentage and pH value in the optimal ranges. Obviously, the greater the light intensity and the hours of light used (in the wavelength range suitable for algae), the greater the growth of the algal mat on the support of the ATS filter.
Furthermore, it was found that the use of the aforementioned filter reduces the activity of the skimmer and of any mechanical filtration.
