Well, that was a shocker. :eek3:

As of last Thursday, I had several beautiful crypt. wendtii plants as part of the foreground of the Betta Palace. After an initial "melt" when they were first put in a couple of months ago, they've been doing great. Then, starting Friday, leaves began collapsing and disintegrating. By Sunday, some plants had lost all their leaves, and none were unaffected. Oddly (to me at least) the line of devastation moves from worst to least on a left-to-right basis. Here are the water parameters as of the 6th:

PH: 7.0
Ammonia: 0
Nitrite: 0
Nitrate: 5
KH: 1
GH: 12
Phosphate: 0.5 ppm
Light: Coralife 28w 6700k CFL (on legs). The light is on 10 hours per day: 7am-Noon, and 5-10PM. (since reduced to eight hours to help fight an algae problem)

I've read that crypts often react badly to changes in the water conditions, and I did add a tiny amount of baking soda to try to bring up the KH. Could that have caused the collapse? (For reference, I change 20% of the water weekly)

For the plants that have lost most/all of their leaves, should I wait to see if there's new growth, or can I assume the roots are dead, too?

This is frustrating: they had grown into very pretty plants. :wall:

What kind of fertilization scheme do you use? Do you think you could have bottomed out on nitrates before the crypts started melting?

My red wendtii melted a couple times for no obvious reason :huh:. Then I moved them to another tank, no melting at all :confused:. I'm afraid to look at them too long. All very low light low tech, similar conditions. I don't know...

For ferts I'm mainly "Seachem Boy:" Nitrogen, root tabs, Potassium, Excel, all added per the instructions. I'll be switching from Leaf Zone to Flourish and Flourish Trace next week, plus adding CO2. (I'm waiting on a DF&S shipment.) The algae problem I'm experiencing I think is from too much light and ferts, but low CO2, but if that also lead to the crypt-crash, I don't know. :huh:

Mine sometimes melt when I add water and it hits the plants directly whenever I do water changes. Could be water temperature changes IMO. But overall, it does have something to do with water conditions. This is very common and nothing to worry about. Just that what was a very beautiful bushy plant now looks like a bare stump. It'll grow back...

Thanks. I'm going to leaves the stumps alone, other than to clean out the melted leaves, and see if they grow back in a few weeks.

BTW, Rocky (my betta) says "Hi, Dad." :laugh:
