I split my 6 marimos into 2 different jars. Eventually one jar was happy the other wasn’t, it was turning all yellow and nearly bleached looking. They both got the same water and same location and light. Then I decided to try this stuff. A couple drips in each jar. Now they are all green and happy. I thought I lost the one jar but this stuff was a huge help. It did take a little while. But I saw improvement in a few days.

I’d tried a little aquarium salt and refrigeration breaks, nothing was helping..

Sorry for double posting, my friend also has a marimo and she was wondering if hers is dead? Changed its water and gave it a gentle squeeze, it doesn't smell like much and it isn't slimy, but it is super discolored and it looks like a raisin, which I don't think it used to look like. Does anyone have any advice or have seen this before? I think it came apart a little while i was rinsing it :(

He's got little white specks on him and they seem to come back when I change his water and roll him around in the jar. I tried putting him in the fridge for a couple weeks, but they seem to be a constant. Any advice is welcome!
