Aquaroche à la Une de la Montagne

■ AQUARIUMS.
Depuis trente ans, l’entreprise de Glénic Aquaroche s’est spécialisée dans la fabrication de roches artificielles pour aquariums : elle est la seule en France.

 

 

 

 


■ REPRISE.
En février dernier, elle a été reprise par Jérôme Levassor. Il ambitionne notamment de développer encore plus le marché à l’international.
Dirigée depuis février par Jérôme Levassor, l’entreprise Aquaroche, installée à Glénic, poursuit son développement à l’international. Spécialisée dans la fabrication de décors pour aquariums, l’entreprise réalise déjà 60 % de son chiffre d’affaires à l’étranger.
Seulement trois entreprises dans le monde fabriquent des décors d’aquariums à base de roches artificielles. Et l’une d’entre elles la seule en France se cache en Creuse. Une histoire débutée à Glénic, il y a trente ans quand Laurence et Jacky Compin, potiers d’art, ont relevé le pari, lancé par un adhérent d’un club d’aquariophilie : “et pourquoi vous ne feriez pas des décors pour aquariums ?”.
« Nos produits vont jusqu’en Chine »
Trente ans plus tard et un marché largement développé à l’international, les fondateurs ont pris leur retraite. Non sans avoir préparé leur succession. En février, l’entreprise creusoise a été reprise par Jérôme Levassor, 38 ans. « Après quinze ans de salariat dans la céramique, je cherchais à reprendre une entreprise de céramique sur un secteur porteur. C’est comme ça que j’ai rencontré Laurence et Jacky. Après un an d’échanges et de discussions, on a pu trouver un accord. » Et continuer dans la foulée des anciens dirigeants. « Notre spécialité, ce sont les décors en céramique pour les aquariums : des roches artificielles les plus proches possibles de ce que l’on peut trouver dans la nature et notamment dans les grands bassins coralliens.
On a d’abord toute une gamme proposée sur catalogue, avec une soixantaine de références et aussi une gamme sur mesure pour répondre à toutes les autres demandes. On a déjà livré un décor pour un aquarium de 15.000 litres ! »
Ici, entre modelage, séchage, cuisson, il faut compter « trois semaines pour sortir une pièce quelle que soit la taille, d’ailleurs. C’est pour ça aussi qu’on travaille sur du stock : en trois jours, on peut livrer tous les standards ». Indispensable pour l’entreprise qui « vend à des magasins spécialisés dans la revente de produits pour animalerie et aquariophilie » et qui surtout réalise 60 % de son chiffre d’affaires à l’étranger.
Un développement à l’international « aujourd’hui, nos produits vont jusqu’en Chine » que Jérôme Levassor compte bien poursuivre en visant notamment les États-Unis et le Moyen-Orient. Et, d’ici cinq ans, « profiter de ce procédé technique pour se lancer dans des activités de filtration ». Ce qui, bien sûr, irait de pair avec des embauches. ■

Aquascaping arches – Interzoo – new

Multi positions arches, for varied and original arrangements.

Easy setting up:

  • Tilt and prop up 2 arches between them.
  • pile them on other arches

On our Facebook page : video of different setting ups –  Interzoo show 2016.
https://www.facebook.com/aquaroche/videos/1188871437790918/

These decors are neutral and can be used as well in fresh water as in reef aquariums.

“Nests ” (with a diameter and a depth around 5 cm), at different levels of the rocks make it easy to install plants in fresh water and corals and anemons in reef aquariums.

The  “1 place” nest can be used as a chock. code 2008

3 arches are available:

  • height  28 cm – code 2028
  • height 38  cm – code 2038

Filter media

LiVe Rock Function Filter

label 12

  • Filter media made of porous ceramic.
  • For fresh or marine water.
  • With high porosity.
  • For bacteria and micro fauna.
  • Aerobic and anaerobic areas.
  • To reduce NH3 NO2 NO3.
  • Live rock function :

    Label Aquaroche: Live rock functionThe development of these modules comes from our vast experience in the creation and manufacturing of rocks/ culture live rocks.
    After colonisation, they are similar to natural live rocks and their porosity is double the Indonesian live rock porosity (porosity 60/65 %)

    Bacteria and micro fauna :

    The difference with other filtration media is that the Aquaroche modules can shelter both bacteria and micro fauna, including microscopic worms which find galleries, wide and deep enough to penetrate to the heart of the rocks.
    wormThese worms and other micro-organisms play an important part in the biological balance and also prevent clogging that often occurs rapidly with other traditional media, with a too thin and homogeneous porosity.

    Picture: Worm among the biofilm secreted by the bacteria.

    Porosity :

    Aquaroche Live rock Function Filter elements have a great deal of open cells of 20/100 µ, linked together by galleries and fissures of 100 µ to 1 mm.
    The shape is a cube of 5 cm, big enough to enable the development of areas poor in oxygen.
    To better imagine the size: a bacterium measures around 1 µ, each element is a micro world cube of 50 000 µ side. To bring it to a human size, if the bacteria measured 1 meter, the cube would measure 50 kilometres.
    Then it’s easy to understand that, to avoid the filter media clogging (which happens with too small and too regular pores) and to make life develop, you need
    • A very good circulation between the pores, the cavities, grottoes and fissures
    • A great variety in the dimensions so that each micro-organism can find its place and can be fed correctly.

    Material :

    The ceramic of the structure is the same as the one for our eco reef plates (to make artificial live rocks), which has proved its neutrality for years. Scientific tests confirm there is no leaching of toxic elements in the water for fish and corals.

    Catalogue :

    2 shapes :

    Simple element (5 cm x 5 cm x 5cm) in a 1,5 litre box – 12 pieces.

    code 401201

    Double element with central hole (5 cm x 5 cm x 10 cm) in a 1,5 litre box – 6 pieces

    code 400602

    Use

    • Do not rinse with tap water but immerse your aquaroche filter media in a “soup” rich in bacteria and nutrients eg. off-the-shelf bacteria products.
    • Put them loose or stacked up in the filter box under a thin coat of pre filtration foam eg. cotton wool.
    • Normal waterflow to provide oxygen.

    Development and maximum efficiency of aerobic bacteria in 4 / 6 weeks (check and follow the evolution of nitrites)
    Clean regularly the pre-filtration foam but never rinse the elements once they are colonised as you would risk to destroy the active bacteria.
    Reduction of nitrates comes from the development of anaerobic bacteria which requires a complicated balance that needs several months to settle (from 4 to 6 months, provided that you do not rinse the elements)

    Awards for aquaroche:
    This year again we were nominated in 2 categories: Export and Vitality.
    It was the place to be to meet sport champions, artists, dynamic companies and associations.
    We had the pleasure to meet the company who makes the first ceramic artificial bones (I-Ceram) with porous ceramic.
    So porous ceramics have a lot of possibilities.

    Large decoration for the shark tank in the Aquarium de liège, Belgium

    Aquarium de Liège – Belgium

    We met Marie, the biologist of the Aquarium de Liège, at last Interzoo show in Germany in 2014. She wanted a big decor for the shark tank ( 4 meters x 4 meters x height 3,5 meters)

    Small clay modell:
    maquette
    This makes it easy to visualize the volumes and know the quantities of rocks we have to make.

     

     

    After we have made all the elements: setting up in our workshop to check the volumes and the scape, then each rock receives a number for the final setting up in the aquarium.

    Hello

    Sorry for asking, but I’m lost with all your items.
    I’d like to start a reef aquarium beginning of next year (size 100x 60 x 60 cm / 40’x24’x24′)

    Feeling concerned with ecology,to limit sedimentation and to have a light decor, I’d like to limit the quantity of wild live rocks.
    I’ am right if I use only  10 kg of live rocks together with your Aquaroches (in the tank and in the sump)?

    My main question is: can you help me to choose a décor for this tank?
    For example, I can’t tell if rock 9007, in the middle of the aquarium is too big or not?
    9007 in the middle and 2 pilars with eco reef plates…
    Or just pilars with eco reef plates…I don’t know…
    or something else?

    Could you help me, maybe with a quick design with codes of rocks?

    I thank you in advance

    Kind regards

    Alain

    I forgot the weir on the left back side. I thought I could use rock 0954

    Think that’s all

    Hi  Alain

    Don’t apologize, it’s normal to ask questions.

    Here some photos with the example you suggested: 0954 in the angle
    1 pillar 0848 and a central rock 9306.
    If we use rock 9007, it can be good but a little too big and you loose the possibility of changing positions of the different rocks that you have with smaller rocks.

    For these 3 rocks, dry weight is about 18 kg, wet around 22 kg

    Your 360 litres aquarium needs at least 36 kg of active rocks (this is when considering 10 % of aquarium volume)
    You can add a complement (minimum 14/15 kilos) of wild rocks, or new eco reef plates or colonised eco reef plates.
    You would also need some eco reef plates to ling the different rocks (bridges) and to create overhangs.

    kind regards
    Laurence

    Hi Laurence

    First I want to thank you for your precse information and the photos, really great !

    I was just asking if you could be kind enough to do some more with other rocks?
    After thinking about the project, it’s evolving…

    As the weir in the left angle is 15 x 25cm, I’d rather see a rock with an angle such as 9516,

    bring 9306 in the middle closer to the rear glas and pillar more in the right corner in the front.

    The idea is to create 2 different blocks with a sort of beach between them to give a depth effect (in yellow on my design)

    You see what I mean?


    I noticed these rocks, but maybe you have other ideas or suggestions? choice is open.

    I wonder if size of theserocks is appropriate, maybe pillar 0848 is too high and 0838 would be sufficient?

    height of water level: 54/55 cm (21’/22′)

    Thanks forthe information on the additional rocks, I’ll take colonised eco reef plates*.

    *In France colonisation of our rocks is made at "La Ferme de Corail".

    Hi Alain
    Here pictures with 9516 in the angle and 0838 instead of 0848.


    It’s not as high as with 0954.
    Personnaly I like it : You can change positions of rocks and eco reef plates and have more possibilities.
    Quantity is sufficient if you want to keep free areas…

    Kind regards
    Laurence

    Alain

    Thank you Laurence !!

    Really perfect ! Exactly what I wanted to do !

    Now I know exactly what I’m going to do when 2 days ago I was still lost….

    Thanks for your kindness and service.
    I ‘ll be pleased if you use my request and design on your website, hoping this will help the community.

    I’m realy happy;-)

    Which décor for my aquarium?

    Here some elements to be able to prepare a décor for your aquarium.

    Dimensions of the aquarium:

    • Length
    • Width
    • Height

    For the footprint of the décor, consider each dimension less 5 centimetres on each side for maintenance and cleaning of the glass.

    Situation in the room, number of visible sides

    Most aquariums have 3 visible sides, with 1 big side against a wall, but some are different:

    Aquarium in a wall: 1 side.

    Aquarium visible on all sides, very often square or round aquariums.

    Aquarium separating two rooms, with 2 small sides against the wall or just one.

    Aquarium in an angle.

    Each type of aquariums brings a different type of décor.

    Free accesses on the top of the aquarium

    Take care of the free accesses between the strengthening pieces.

    For aquariums integrated in a wall, think that you’ll have to bring your accessories and rocks over the aquarium.

    We made a special big décor for a very large aquarium ( 6 meters long, 1 meter wide et 2 meters high) with elements that had to be under 30 cm as the way was very narrow. Not very easy for people who set up this décor!
    Aquarium 6 m x 1 m x h 2 m, passage disponible 30 cm

    Weirs and different materials

    You have to take their dimensions and position into account to imagine your décor, same for tubes.

    Design

    Prepare a design with 1 cm for 10 cm, then it’s easier to have the right proportions: front view and top view
    Then design the main lines of your décor.

    Exemple de plan

    Choose your rocks

    Depending on the type of aquarium (fresh water, cichlid fish, reef aquarium,  fish only…,) choose your décor:

    • central décors with many ways
    • grottoes
    • arches
    • platiers
    • backgrounds

    Eliminate all décors that are too high or too big:
    For a 50 cm high  aquarium, the tallest piece will be under 45 cm.

    See catalogue and  examples.
