I've had terrible luck with Cabomba. It just melts no matter what I do, even with CO2 and high light. Anyone else struggle with this one?

Cabomba's a pain, dude. I tried it in my 20-gallon with Fluval Plant 3.0, and it still turned to mush. Maybe it's the water hardness? My tap's like 8 dGH.

Cabomba's notoriously finicky. It needs stable params and soft water. Mine thrived after I switched to RO water and kept KH below 4.

Dwarf Hairgrass for me. It's supposed to be easy, but mine just sits there like a sad carpet. Even with root tabs and ADA Aqua Soil, it's barely spreading.

I had the same issue with Dwarf Hairgrass until I cranked the light to 8 hours and added liquid carbon. Now it's creeping, but still slow.

Java Moss. Sounds foolproof, right? Nope. Mine turned brown and slimy in my low-tech tank. Maybe it's the temp? Tank's at 78°F.

Java Moss needs flow. If it's stagnant, it rots. Try placing it near your filter outlet.

Mine did the same till I trimmed the dead bits and tied it to driftwood. Now it's lush.

Anacharis. It grows like crazy, then suddenly disintegrates. No idea why.

Anacharis hates high temps. Keep it below 75°F, or it'll melt.
