Troubleshooting
Dwarf Baby Tears problems — and how to fix them
Dwarf Baby Tears (Hemianthus callitrichoides) 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.
Carpet lifting and floating
Oxygen bubble accumulation under the carpet mat causes it to detach and float. Gently press sections down; this is more common with very high light and CO2.
Failure to carpet — upright growth
Low light is the primary cause. Ensure PAR at substrate is above 50 and CO2 is being injected consistently.
Melting after planting
Newly planted HC often melts as it transitions from emersed to submerged growth. Keep conditions stable and wait for new submersed growth to emerge.
Algae smothering the carpet
The tiny leaf surface is quickly overwhelmed by green dust algae in unstable conditions. Stable CO2, consistent lighting, and Amano shrimp are the key counter-measures.
Brown or yellowing patches
Often indicates nutrient deficiency (especially iron or potassium) or CO2 shortage. Increase dosing and check CO2 diffusion efficiency.
