A lot of people keep talking about there plants melting... can someone describe what this exactly looks like? If a plant melts will it grow back eventually? Why do plants melt?

Why does this affect some plants and not others?

The plant fades and "dissolves" into the water. Most will grow back. They do this if something in the water has changed. Crypts do this a lot.

there are many reasons plants could melt. here are some examples:

excess Mg can melt some plants, this will happen suddenly.

lack of co2 will melt plants too, but it will show up slowly, this happen without showing any deficiencies on plants such as iron, Kno3 etc. green healthy leaf can start to melt away slowly when co2 and circulation are weak.


very high KH can also melt plants, but some plants don't mind it at all.


very high GH can also melt some plants


ammonia can also melt plants, this happens fast too.


those are some common cases of plants melting, most worse one is weak co2 and circulation.

plant can recover if they melt, but it really depend on rooted type plants vs stem plants, root type can loose all their leaves and they will pop out of no where, blyxa japonica is a good example. stem plants are hard to recover once they are melted, however if the plant is half way melted and then you trim that part and make the changes to the reason for melting, this plant might take off.

I can add a personal experience with stem melts. One of the first stems I ever got was water wisteria. It was bunched with a weight, I buried the ends in the substrate and it started to melt away within a day of doing this. I lost every single stem, they turned to complete mush! A few weeks later, I found a tiny piece that had somehow survived. I let this piece float and it began to root, so I simply placed it by the substrate. Now, this one tiny piece that survived a complete melt has produced so much wisteria I don't know what to do with it!!
I'm pretty sure it's ammonia. One of my plants that was doing really great... just "melted" away. I left the roots in the tank hoping they will eventually come back. It's so strange how it affects some plants and not others.
to prevent plants of all kinds from melting float them in the tank for a day before planting this will really help against melting quite a lot
Crypts melt because there's a change in their conditions. They grow leaves that are tailored to the light, fertilizer, and other conditions in the tank that they are in. If they are moved and the conditions suddenly change, the leaves will melt and they will grow new leaves that are tailored to the new conditions.

The leaves turn yellow and start to go transparent and mushy.

effect of ammonia is less effective when ph is below 7< because ammonia is in ammonium form.

I keep hearing this about crypts, but I have never had this problem regardless of where I get my crypts.
Sometimes stress when planting can melt plants. Such as crypts. It happens as if the leaves are slowly being chewed.
