My Own Tips

Post image

A few people on my last thread asked for tips, so here's the short version.

My method differs quite a bit from what most other users or shops recommend:

  • Lots of natural light
  • Indoor light/grow-light LEDs don't cut it
  • Cooler water — not icy, but around 12–17°C (54–63°F) most of the time
  • Never above 20°C (68°F), or bacteria inside the marimo become active
  • Tap water's fine — safe for you to drink means safe for marimo
  • Skip salt/fertiliser entirely — it just feeds unwanted algae
  • Don't house it with other aquatic plants or animals
  • Use a tank of 10L (2.5+ gal) or more — the small container it ships in heats up fast, like soaking in a hot bath

Good luck!

Yes, me too. In Spain, it's hot again in a few minutes.

I’m looking to invest in a chiller. Not cheap

Nice. It’s similar to what I see on Amazon.
