I recently started DIY CO2 on my 20g and I've noticed that my crypts have started melting a bit. Normally this wouldn't bother me except for the fact that these are plants that have been thriving in this tank for a year without CO2 and now they get CO2 and they start looking melty? I don't know if it's coincidence or not.

My water parameters haven't changed much from the CO2 injection, and I'm running an airstone at night.

Any input?
 
I have heard that Crypts tend to melt more in Co2 and high light. My observation is that crypts melt when changes are made and return and thrive again pretty quickly. So to me it's more of an adjustment to the changes thing than the co2 actually melting them. I will also say that I am no crypt expert, but have seen tanks (Reiverex) that have some of the biggest crypts I have ever seen and are high light high co2 level tanks.

I'd wait it out and see if you have repeat problem before being too concerned.

My crypts did the same thing....I put CO2 on and bumped the light up to 3.5wpg and they all melted...but slowly they are growing back so i wouldnt worry about it....you might want to clean out the melted crypt leaves and roots though...the are pretty disgusting after they have been in there awhile...and they do STINK
 
hmm.....my crypts have been uprooted and moved 3 times since i got them, and they have never melted. first i pulled them out of the pot from the pet store and planted them in my 10g, then i moved them from my 10g into my 20g, then just a few days ago i uprooted them to rearange the tank. maybe mine are special, lol.
 
I've got 5 different species of crypts going in my tank and they don't all melt the same.

My willisii have never melted and have been with me the longest, at least two complete overhauls. I have a wendtii that seems ready to melt at the drop of a hat. Melted flat, came back and melted again (came back again, seems ok).

The other three are in the middle. Petchi seems hardy, crispatula a bit less so, parva almost as bad as the wendtii.

They vary in their delicacy but they all seem to come back when they've had a chance to acclimate.
