Who Gives A Fish Forums

Thanks for the tips, everyone. My tank's been up for 5 months, nitrates are around 15 ppm. I'll try the 45-degree cut and Flourish dip. Appreciate it!

I've been trying to propagate Rotala in my 20-gallon tank but the stems keep melting. I'm using CO2 and high light, but the new cuttings just don't take. What am I missing?
