Marimo Bowl Setup

Ok… It appears that I screwed up somewhere… This was supposed to have been posted BEFORE the Marimo Completed post. *sigh* Although the schedule date was set right the fact that I must have clicked ‘Save’ and not the ‘Schedule’ means I dun did an ‘Oopsie’.

Good grief. Oh well… You can have it now.


With me now having new Marimo babies. I decided that I will make myself a separate Marimo ‘tank’ or bowl? Setting up something like this isn’t as easy as just “Get bowl, add water and rocks, and then pop in the Moss balls.” No Siree!

The first thing I learned when I set up my first fish tank was that there are a lot of things that will infect water! Ok, it’s not that drastic but if you want to bring stuff in from outside or whatever, you need to make sure it’s clean.

I got 2 lots of stones from my garden and I had some glass beads for some reason… And the jar above from an old gift my daughter got. It had just been gathering dust so she gave it to me and I put it to use.

I picked 2 types of stone and the beads because I have no idea what will look good in the jar. This way I can try all 3 and discard whichever I don’t like.

There are a few ways to clean things for an aquarium. Bleach, boiling and baking are the more common. For my set up I decided to bleach the jar and boil the stones and glass beads.


While baking is the easiest I don’t know what kind of glass the jar is so I don’t know if it will hold together at the 200C needed to kill off germs. So I went with using bleach to clean the jar instead. A mix of 10:1 water/bleach and leaving it to soak for 24 hours, then a really, REALLY good set of multiple rinses with clean water. Then, when done, leave it to air dry for a couple of days to evaporate any bleach not cleared already.


The stones and beads I decided to boil for 20 mins on a high heat then leaving to cool. If you do this then you REALLY want to be careful. Those stones get very hot and they stay hot for a lot longer than you may think.
Also, don’t be tempted to run them under cold water… Very hot rocks and glass suddenly plunged into rapid cooling have a chance to do bad things. Just let them cool naturally. B-)


I chose to let the water cool in the pan for a half hour then poured them out into an old colander to cool from there. After an hour they were still warm. O.o


You will notice that I actually cleaned a LOT more than I would likely need. Better to have too much than not enough and have to repeat the process!

I also put a jug of water on the side to age. Now, I know that I don’t really need to do this but I didn’t want to take any water from the fish tank they are in now, because of algae pollution. And to be honest, I couldn’t be arsed to work out the minuscule amount of tap water cleaner needed to sort out the 900 mls I needed. So “aging” it is. B-)
Besides… It’s only a Moss ball… No fish will live in there.

So, in a couple of days when everything dries off properly and gets a good rinse I will make up the bowl and see which I like!
