Wow, isn't that bad for the fish though? xD

Hi...I'm new here. Just got my nano and giant marimo from leeyung ytd. Would like to ask...other than tap water, can i use those filtered water like diamond water??

I think tap water is already okay..
I use usual water (with chlorine)=="
and yes the results is good, my Nanos all so fluffy and the texture is really improve alot..

Haha, great to hear that, if you do not have any fishes in the tank/bottle, no problem for using direct tap water, save a lot of cost in long run
Haha, betta can sustain chlorine in some cases Yeah, if you are having Marimo only, tap water more than enough and the results are pretty good
Very neutral pH level you have ur otto superb cute haha

Guys, will it be better if I use chilled water from the water dispenser as I dont think I can put them in the fridge overnight. When you guys put them overnight, do you just use a container which covers just enough for their height? Please advice. Thanks.

Hi shifus,

few questions need to be asked in here.

1. 1.5feet tank can fit in how many gaint and nano marimo?

2. what type of lights are required? i am using t5 for my planted. i guess it will be too strong for them. any picture of the light i can used? or just normal room light? how many hours need to on?

3. when do water change, how many % need to water change? 100% or like planted tanks 30%?

4. if i got a lot marimos, all put to fridge at night, and next day put to tank? whats the effect?

5. can use ice water to fill in the tank? my tank is still emtpy now. so, when i start, possible to pour in all cold water? is anti chlorine needed?

6. can i throw many cubes of ice in there anytime?

7. If i am back to my hometown, and possible if there is no light for a week?

please advise and sorry for all those noob questions.

Added on November 8, 2012, 4:24 pmadd on: need to put salt???

1. 1.5 feet tall? How long? How wide?
2. I'm using one 24w T5 for my 60L, no problems. Also, see below and read the first page.
3. I've done anywhere between 30% to 100%. Doesn't seem to make a difference. Just do your best to avoid huge changes in temperature or other parameters.
4. As opposed to a few marimo only?
5. Where are you going to get that much ice water? Also, see below and read the first page.
6. Just avoid thermal shock. Letting the ice melt on its own should make it gradual enough.
7. See below.

Thanks bro.

put in cube ice to make the water cold always. i got a big huge fridge. i thought they like cold cold. by the way, it will kill them if the temperature change a lot by throwing ice cubes frequently (except sat n sun)

Hi guys. I got my first marimo as a gift from my colleague a few days ago. I have some concerns about it...

I'm not sure if this is a problem caused by post as there was a delay in delivery and the whole batch spent 7 days in transit. They came in poor packing and quite dry (I think the supplier's from S'pore, hm; we're from Kuching btw).

So my marimo's not as brilliant green as the ones I see here, but yellowish/pale green, and has while/yellow specks here and there.

I read salt and cold water helps. It's also not pearling, something healthy marimos do, or so I read (correct me if I'm wrong, I'm pretty new to this thing)

I'd love for help/tips to help marimo recover. How long will it take at worst/best?

Also, just wondering about water changes.  Is there such a thing about changing water too frequently?

Depends. If you're swinging the temps around 10C over short periods (1-2 hours) of time, it could be bad. Better to keep it constant, even if it means having a higher average temp. Better yet, why not consider getting a chiller if you're so worried about temps? (Or chuck the whole tank in your enormous fridge.)

Again, use search function, it's been mentioned a few times, but I'll give you a freebie this time.

Leeyung, the famous guy who sells marimo on this thread (and other places), says marimo "food" and "salt" are essentially useless besides making the owner feel better about themselves, and are probably obscenely overpriced regular aquatic supplements. Think about it, they're selling these magical vials of marimo fairy food, but don't bother telling you what's in them. They grow in lakes where many other plants grow, taking in the same nutrients as they do. You may try regular planted tank fertilizer, but leeyung says he's tested them with no noticeable effect either. Before you question his judgement, remember he has nothing to gain by claiming these things as he doesn't sell supplements himself.

Many of the principles regarding the care of planted tanks apply to marimo. The rule is plants only grow as quickly as the lowest available nutrient allows them. You may have all parameters ticked off except one, and still not improve growth rate.

1. Nutrients: Marimo grow very slowly and thus absorb nutrients at a very slow rate. This is why they don't respond very well to added fertilizer or "food". That said, water changes every few weeks will help maintain available nutrients, and you may supplement with a little fertilizer in case your tapwater isn't balanced.
2. Light: Marimo live at the bottom of lakes most of the time. They can survive on very low light and thrive in low to medium light. From what I've seen, marimo only pearl when there is a LOT of light shining on them, but in the winter, Lake Akan freezes over, blocking out most of the sun for months. You could take this to mean marimo can persevere without light in low temperatures, but you didn't hear it from me. I've seen some people claim cooler temps encourage growth, but Leeyung recommends higher temps (around 26 if I remember correctly)
3. Filtration: installing a filter will aerate and keep the tank clear. Again, just to make sure the marimo receive adequate CO2 and O2.
4. Salinity: There's a theory going around that Lake Akan used share its water supply with the sea, and that the current measured glacial growth rate (5mm a year) is due to the fact that Lake Akan no longer receives this saltwater and salinity has fallen. Carpet marimo are observed to grow "thickest" where the lake receives saltwater from nearby springs. Read here:

http://www.marimo-web.org/en/b-spherical/b3-salt_water.html

Some people (like the post on the first page) recommend a 5% concentration saline solution to revive sick marimo. This is even more concentrated than saltwater, so I think you have a lot of room to play with setting up an appropriate salinity for your marimo.




    

by the way, what is the actual shape of a marimo? some i see is flat , some is sphere, and some is like sphere but bengkak a bit (for giant). and for the nano, is it really full round? some i see, like the cebisan moss, and ppl just roll it round.but in a short time, the roll will open, n become a flat marimo
ps: Regrettably a lot of this is pseudo-scientific opinion and anecdotal advice. As such nobody can claim to be the absolute authority on marimo care. (Unless you're a marimo scientist.)
