Troubleshooting
Bacopa australis problems — and how to fix them
Bacopa australis (Bacopa australis) 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.
Grows upright, won't carpet
Carpeting needs high light; under low light it stretches vertically. Increase intensity and pin or trim stems horizontally to encourage spreading.
Thin, sparse growth
Low CO2 or nutrients give open, weedy growth. Add CO2 and dose a complete fertiliser for density.
Lower layers brown out
Thick carpets shade and kill their own base. Trim the top growth regularly to keep the mat healthy and light-fed.
Conversion melt
Emersed stock may shed leaves when first submerged. Keep parameters steady until submerged growth establishes.
