algae aquarium.
Green algae to clump are single-celled green algae that reproduce both sexually and asexually by zoospores.
spores, separated dall'alga parent, form a new strand that immediately begins to reproduce.
The algae appear to clump in the tank as cotton balls deep green, usually attached to rocks or wood brightly lit, do not attack the plants, and are often considered weird decorations and furnishings for logs and tolerated.
Usually values \u200b\u200bof nitrates and phosphates are very high key triggers for these algae. Vegetarian Fish Removing only the parts young and tender.
key triggers:
have needs very similar to those of higher plants, and aquarium are in the right conditions to develop, usually prefer clean water and just move
Elevated nitrate and light is not suitable (wrong strength spectra, lamps or old) will favor the emergence and development.
However there are not harmful to plants and fish, because they grow only on furnishings, but appeared to be a serious wake-up call.
Main methods of prevention:
The best way to contain the growth of algae in general and in particular is to put these plants in the best position to compete.
Choosing the right light spectrum (typically between 4000 ° 6500 ° k and k) and maintain low levels of pollutants from decomposition (mainly nitrates and phosphates), preventing their appearance and limiting their spread.
organisms antagonistic
Fish algae eaters eat only the young and tender seaweed, and are useful to prevent its occurrence, but unnecessary to control an infestation already underway.
Shellfish preferably act in the same way, but if kept in the diet reduced eat it willingly.
gastropods such as apple snails and neritine are effective, but Their action is completed in time long enough (they are snails!).
Chemicals effective:
Use of chemicals to combat algae green tuft is not recommended, as these algae needs very similar to those of higher plants, and any chemical treatment would have detrimental effect on plants and also would have limited effect and only temporary effect.
Success Strategies against infestations
The most effective weapon to combat infestation by a green tuft are crustaceans algae eaters such as Caridina and Neocaridina , who are greedy.
The mechanical removal of clumps is a viable alternative, but is time-consuming and tedious.
For overcrowded tanks the only remedy is to reduce the number of fish and if possible increase the plant biomass by introducing other plants.
The use of synthetic resins is a temporary palliative, unless they are used on a permanent basis (expensive as well as artificial), also just an oversight and the system collapses rapidly.
In practical ways to combat this type of algae are two: eat them or make them die of hunger ... the first street is repressive, the second is preventive.
