Malamix Koi Hacienda

Malamix – the miracle cure

Malamix – We are convinced of the product.

But, that you know already.

For people who do not yet know the product, here is a brief description: Malamix17 is a liquid of 17 natural ingredients (eg ginger, calendula, aloe vera, echinacea etc.) developed by the Belgian veterinarian – specialized in koi – Maarten Lammens. This liquid (I call it “herbal liqueur” 😉) helps the koi to increase their own defenses and thus improve their immune system. That means that they become more resistant and strong against bacteria and parasites.

Healthy koi thanks to prevention.

We already know that “prevention is worth more than cure” but Malamix17 can also cure. We use it when we see that the koi are stressed. Stress is very obvious in white koi since they become “pink” (because the veins become more obvious). With a simple treatment of Malamix17 (1 liter of product is good for 10,000 liters of pondwater) and the koi are cured.

We call “stress” to “undefined” situations such as:

  • introduction of new koi in an existing hierarchy
  • drastic temperature changes
  • after a chemical treatment of the pond water
  • etc.

Healthy Koi thanks to an efficient and natural product.

By the way: As I am so convinced of the product, I asked Maarten if I could use it, too. His answer was “in principle yes, if it were not for the substances that I have incorporated to increase the biological bacteria in the filter” 😉

And since there was so much positive reaction, Maarten worked to incorporate these ingredients into koi feed.

Talking colloquially: the feed is like the “Actimel” – it works from inside.

And – to return to the original reason for writing this article – to show that it is not only us who is happy with the product, here are some voices of our clients:

The food is great. The koi like to eat it and the water does not turn turbid. However, I only give them as much as they eat in about 5 minutes. In winter little and in summer more. The other feed that I had previously used, was always leftover.

The Malamix feed goes well, I at least see them healthy, beautiful and with a good growth.

(Miguel, Balearic Islands)


Since I use Malamix I see my fish calmer and with less stress, therefore, its use is totally advisable.

(Antonio, Málaga)


I have been using Malamix mixed with Ichi summer or winter according to season for more than three years now and I am very happy because I have never had a sick koi so far, so I will follow the same diet at the moment.

Koi Hacienda pre-filtro

Do I need a pre-filter for my koi pond ?

For this question there is no general response. We have to consider several aspects of who the question posed to us and we must explain what a pre-filter is.

A pre-filter is a filter that is installed in front of the main filter. The purpose of the pre-filter is to remove dirt BEFORE it reaches the main filter.

It is very useful if you have a difficult main filter (access is difficult) or laborious (remove 80 brushes of 70cm each, which is a lot of work) to clean. Then it is a huge advantage to have a pre-filter installed and thus reduce the cleaning of the main filter to (for example) only once a week.

Another appropriate situation to install a pre-filter: When one has started “little by little” with the pond and the koi, it will probably come to the situation when the existing filtration can not cope with so many koi / big koi. It would seem likely to adapt the complete pond, but often there is neither time nor money to do it. In this situation the incorporation of a pre-filter can save the situation, because it removes a lot of dirt before it reaches the main filter and thus decongests it.

A third reason to use a pre-filter is the filter bacteria in the main biological filter. These bacteria are sensitive to cleanings. Obviously it should only be cleaned with untreated water (chlorine would kill them right away), but they are still fragile and with a strong water jet quickly thousands of good bacteria are eliminated. If we use a pre-filter, we will reduce the amount of cleaning of the main filter and let the bacteria live quietly.

A pre-filter is then advisable

  • if you notice that the filter can not cope (either because the good bacteria are eliminated or because too much dirt enters). This “not enough supply” is expressed through turbid water, fish scratching, high level of ammonia etc.
  • if the cleaning of the main pond is difficult and / or laborious (which in the end will result in cleaning less often and / or removing the desire to have koi)

The pre-filter recommended by Koi Hacienda is called MultiCyclone of the famous Waterco brand. The manufacturer announces that it filters 80% of the dirt that would normally reach the main filter. We can not confirm the figure, but we have very good experiences using the MultiCyclone in our facilities (before arriving at the main filter which is a UB60 filter with beads).
