How to eliminate dinoflagellate algae in the aquarium:causes, what to do and how to eliminate them from the marine and freshwater aquarium. DIY algae filter.

According to a relatively recent study (dated 2015), potassium oxide-based compounds, contained in the glass of the tank, would raise the risk of algae development in both fresh and marine aquariums. Generally when we talk about algae in the aquarium, which smear the bottom and glass, we refer to diatoms, unfortunately these are not the only algae that we will face.

While diatomaceous algae are typical in maturing marine aquariums, the dinoflagellate algae they can explode at any time. The cause? A spike in phosphates and nitrates.

Dinoflagellate algae

Organismsdinoglagellatesthey are nothing more than microscopic algae that have a flagellum, that is, a “whip” structure with a typical undulatory movement. Dinoflagellates are also known by the name of pyrrophytes or dinoficee. They represent one of the most important phytoplankton groups both in marine and freshwater environments and, if their presence is not massive, they do not represent a threat to the small aquarium (marine or freshwater).

Foreliminate dinoflagellateson the market there are ad hoc products, to be dosed in coffins to the volume of the aquarium and above all, in the case of a marine aquarium, to be administered with lights, in the evening, when the activity of the Zooxantellae (a population of flagellate algae essential in the marine aquarium with corals) is at a minimum.

When administering products to eliminate dinoflagellate algae, remember to eliminate zeolites and activated carbon from the filter or from the sump and, in the case of a skimmer, skim very wet.

Specific products seem to be the only safe solution, as do-it-yourself methods may be of modest effectiveness or only be useful in case of infestations bydinoflagellatesof modest entity.

How to do?
Everyone recommends bringing KH to very high values, but this doesn't seem to be an effective solution.

There are also those who recommend administering iodine - with the lights out - directly on the rocks to be treated, which are rich in dinoflagellates. Among others remediesDIY, hydrogen peroxide is also recommended.

How to eliminate dinoflagellate algae with hydrogen peroxide

The doses foreliminate dinoflagellate algae with hydrogen peroxidesee the use of 1 ml of hydrogen peroxide (3% hydrogen peroxide) for every 40 liters of water to be treated.

THEdinoflagellatesthey are really hard to get rid of and are very quick to reproduce.

Algae filter: eliminate dinoflagellates in a natural way

Dinoflagellates compete with all higher algae. A good way to eliminate them is to adopt an algae filter. There are different types of algae filters on the market but those who have a sump can do it yourself.

You can divide a compartment of the sump for the breeding of superior algae that can act as a filter and help you eliminate dinoflagellates.

You can use plexiglass and silicone sealant to get the ideal compartment. The algae to use are theChaetomorphabut be careful that the tank where the filter will be made must be well lit (at least 12 hours a day) and have a movement of around 10 - 20 times the volume of the tank used as a filter. To be effective, the tank you get to make a DIY algae filter must be at least 20% of the volume of the main aquarium. 20% is a perfect estimate as a large part of your aquarium is occupied by substrate, plants or corals! For the DIY algae filter you will not need sand or other substrates because Chaetomorpha algae grow in free form.

Thealgae filter it is generally made with Chaetomorpha or Caulerpa (which however needs a sandy substrate), in both cases these are superior fast-growing algae able to absorb nitrogen, phosphorus and other essential nutrients for the development ofdinoflagellates.

Protocol for the management of algae in the aquarium

If there is not yet a large infestation, you can take advantage of an algae growth control protocol. In practice, these are products that keep the levels of phosphates and nitrates low, essential for algal proliferation.

    I apologize for interfering, but could you please give a little more information.

    It is interesting, while there is an analogue?
