Cryptocoryne wendtii 'Brown' problems — and how to fix them
Cryptocoryne wendtii 'Brown' (Cryptocoryne wendtii 'Brown') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crypt melt
Sudden leaf dieback after planting or parameter changes. Don't uproot; keep conditions stable and new submerged leaves regrow from the rhizome within weeks.
Algae on old leaves
Slow growth lets algae settle on outer leaves under strong light. Balance light with nutrients/CO2 and trim affected leaves.
Stunted, pale growth
Iron and root-nutrient deficiency in inert gravel. Add root tabs and a liquid micronutrient supplement.
Failure to spread
Disturbed or rootless plants stall. Leave undisturbed in nutrient-rich substrate so runners can establish.
