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!






Marimo Completed

This morning I gave up waiting and decided to make it up today.

I took all my bits and, using all the stones, had a go to see which I liked. In the end it was the pebbles I liked. I put them all in the tub and removed some till I was happy.


In the end I got to here. It’s roughly 1/3 medium to 2/3 water. I have no idea if that is aesthetically good or not but I am happy with it, if you choose to give it a try then you will likely go with something else.


I then added the two Marimo and put the lid on.

I took the extra stones back outside and then took the completed Marimo bowl upstairs to the bathroom.


It will sit in the sunlight for a couple of days so that the bubbles disperse. Once it has settled down again I will move it to my room. It may be a North facing window but its actually not so bad. It gets a fair bit of diffused light.

BTW… If anyone wants more info there is a great channel on YouTube that has lots of vids on the subject. Wendi Phan

Mini Marimo Me’s!

About 4 years ago I bought a Marino moss ball for my fish tank. It did really well and, well… By accident I managed to break it and turn one ball into two! *rolls eyes*


Fast forward to today and I seem to have found that my two Marimo balls have now had kids… I’m not sure this is how it’s supposed to happen in moss ball procreation, but I’m not going to argue… B-)


Everyone, say hello to Kael’Thas. That’s my daughters Red-tailed Shark that managed to photo bombed me on just about all the shots that came out roughly in focus. B-)

I’m considering taking the two smaller ones out of the tank and putting them in special bowls just for them and treat them like house plants, which is closer to what they actually are, rather than tank ornaments and filters.

Marimo make great pets too. Kinda. You move them around, talk to them… You can even take them outside and teach them to play catch! Or maybe you can play catch with them? Either way fun can be had with them.

Imagine a softer, wetter pet rock… except these grow over time while pet rocks don’t. B-)
