Cryptocoryne wendtii 'Red' problems — and how to fix them
Cryptocoryne wendtii 'Red' (Cryptocoryne wendtii 'Red') 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
Leaves dissolve after replanting or water-chemistry changes. Leave the rhizome in place; fresh submerged growth returns once conditions stabilise.
Loss of red colour
Greens out in dim light or low iron. Raise light moderately and dose chelated iron to restore the red-bronze tones.
Algae buildup
Slow growth under excess light allows algae on older leaves; balance light, nutrients and CO2 and prune affected leaves.
Slow establishment
Newly planted Crypts often pause for weeks. Be patient and avoid moving them while roots anchor.
