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


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

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


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;-)
