Taxiphyllum alternans problems — and how to fix them
Taxiphyllum alternans (Taxiphyllum alternans) 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.
Loss of neat shape
Low flow lets fronds collapse into a shaggy clump instead of tidy tiers; increase gentle circulation to restore the draping structure.
Algae on fronds
Excess light or nutrients coats the fine fronds with algae; balance lighting and CO2 and add algae-grazing shrimp.
Brown inner growth
Dense mats shade and choke their interiors; trim regularly so light and water reach all layers.
Slow establishment
Newly attached moss grows slowly at first; keep it undisturbed with stable parameters until rhizoids grip the surface.
