Frequently Asked Questions

What is "crypt melt" and should I panic?Crypt melt is when leaves rapidly dissolve after a change in water parameters, lighting, or transplanting. It's usually not fatal — the rhizome typically survives and regrows new leaves suited to the new conditions within a few weeks.
Do Cryptocoryne need CO2?Not strictly, though CO2 and a richer substrate speed up growth and reduce the chance of melt after transplanting. Many species do fine long-term in low-tech setups once established.
Should Cryptocoryne be planted in substrate?Yes. Unlike Anubias, Cryptocoryne is a true root-feeder and should be planted in substrate with the crown left above the surface.
Why does my Cryptocoryne look different to the photos?Crypt leaf colour and shape can vary significantly with light and water hardness, and even between plants of the same species, so some natural variation from photos is normal.
