apa sal bro become cute_miao this time?

my marimos from lee yung. haha abit messy with my drawings sorry   

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.

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:

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.)

In its basic form, marimo is an algae filament - strands of algae only a few cells wide. Depending on the enviroment, they can become entangled and form any of the shapes you've seen. They're all marimo, but the most famous appearance is the ball shape. "Cebisan" moss (which you should be calling algae), start best as nano marimo, which bond together more strongly the longer they live. I've made a few of these myself. If they fall apart, they're too big; split it up and start over.

What is "brightly K"?

Friend bought me a marimo as my birthday present.

I have been reading the 128 pages of this thread  , and wanted to know more about the lightning.

I know that we cant use UV lights as it will kill the marimo.

Question is, i got this light previously. But i already throw the box away. so i dont know whether this light can be used or not. please advise.

p/s: my tank is 45cm x 30 cm x 33cm

none fish eat poo XD
If you have another plants beside of marimo, poo is good for their nutritions
if you dont like, then syphon the poo by using a small hose (really efficient!)
by sucking them via ur mouth (but don't swallow it!)

when your tank is still new, remember to give ur bottom fishes some food, like algae wafers
if you don't have algae in ur tank yet, give the otto cucumber, drowned it to the bottom by binding it to a small stone
my otto eat cucumber in the first time, now they always eat algae/slime in the tank. Only feed the Bettas now..

I think u don't want to add Chinese Algae Eater, because when they're getting Bigger they sometimes kills other small fish...
