Other than the easy maintenance plants like Mosses, flogbits, s Nathan and of course algae, I hardly Can grow plants in my tanks. So replacement is the way for me every now and then...

sometime easy plants like hornwort and anubias also slowly melted away on me.
Some are ok in one tank but not the other, and i could not figure out the reason(s)/cause(s).

Most of my tanks are well lid, no substrate and no ferts in soft acidic /black water.

Any sifu can explain the chemistry set off in the water from melting hornwort? And what to watch out in avoiding melting anubias.

Thanks for helping.
