I've kept C wendtii in two of my tanks for over 10 years. A few months back, I had a full meltdown in one of them. Lost every leaf, though they are coming back now in that one. All other plants are unfazed. I've had my share of crypts melt shortly after purchase, but never had mass melting in tanks until then. Fast forward to this week and it's happening in another
tank! In this case, it's particularly bad because there's probably a bushel of Cryptocorynes.
Here are before pics:
Here's a today shot:
I use tap water on these two tanks, and am blessed with soft neutral mountain reservoir source water. It's always grown plants as well as remineralized RO for me.
Parameters are as follows:
No testable amounts of nitrogen except NO3, which is <10, though these values are expected to rise from all the imminent leaf decay.
Tank is dosed lean with GLA ferts since there are shrimp in it. No glutaraldehyde products used. In the past, I was apt to skip water changes and fertilization from time to time, and the crypts weathered that well. But I have been really on top of these tanks the last few months, and it is now that I'm running into problems. Not suggesting that Cryptocorynes like neglect with that statement, just pointing it out. Besides the series of partial water changes I'm up against, any advice? Is there anything I can do going forward to prevent this from happening again? Thanks in advance.
