zayackylepga Posted November 30, 2021 Share Posted November 30, 2021 Have some serious crypt melt two days after a 50% water change. Would that bring on this sudden melt? Previous healthy leaves as of a day or two before. Parameters stable, with hard water as the main water source around here. Anyone else experience this after a large water change?

lefty o Posted November 30, 2021 Share Posted November 30, 2021 a water change alone should not cause a melt. how long have the crypts been in the tank? 1 Link to comment Share on other sites More sharing options...
zayackylepga Posted November 30, 2021 Author Share Posted November 30, 2021 8 months, and have been doing really well. Maybe temp of the water? Did not match it perfectly and the tank was slightly colder after the water change Link to comment Share on other sites More sharing options...
lefty o Posted November 30, 2021 Share Posted November 30, 2021 yeah, thats odd. it should take much more than a moderate temp change to do anything. 1 Link to comment Share on other sites More sharing options...

Did you change more water than that? Of course my tank is deep, so they may not feel the temp change as much.... it's 24 inches deep. Link to comment Share on other sites More sharing options...

zayackylepga Posted November 30, 2021 Author Share Posted November 30, 2021 Pretty up to date with root tabs but little to no nitrates in water after the water change. Would taking out the nitrates with a water change have that much of an effect? I know crypts are primarily root feeders, how much do they actually take in from the water?

Would taking out the nitrates with a water change have that much of an effect? I know crypts are primarily root feeders, how much do they actually take in from the water? I’ve read that Crypts can actually take in quite a bit from the water to the point where they can actually be grown as epiphytes. Even take in ammonia directly. The closest I’ve come to growing as epiphytes is several Crypts I’ve had in a bare bottom tank that was serving as a QT for several weeks. They did a hard melt in the first couple days when I got them and I just haven’t gotten around to doing anything with them, yet, since they melted so hard I couldn’t even tell what they were going to look like. Some are supposed to be Flamingos. We’ll see, but I have my doubts about them being Flamingos. I've never had any Crypts melt from even whopping big water changes. Tank changes where I disturbed the roots, absolutely will melt. 1 Link to comment Share on other sites More sharing options...

No. 50% water change, with a chemistry differential large enough to annoy the leaves, and especially if the water current during the change moved any substrate around the roots? I have experienced that😬 As long as the rhizome was not damaged, the crypts will come back stronger than before. Link to comment Share on other sites More sharing options...

I'll grab a couple pics when I get home today. I did that, too. Had a crypt jungle that never got root tabs or ferts. It did great until I lost my light once. The tank went a few days with little but the ambient light from the room until my replacement light arrived. Had some serious melted, then it all bounced right back. Stayed that way until I broke the tank down to rescape it early this year. Here's how it looked before rescaping. It had been like this for a couple of years after the light fiasco. No root tabs or ferts of any kind. A single common pleco as the only tank occupant for at least that couple of years (he got to where he killed anything I put in the tank with him, so he remained alone for quite some time). I'm currently having Crypt melt, though, in my little 5g. I changed the light on the tank about a week or so ago, which increased the lighting from low to medium. The Crypt wendtii 'tropica' started melting by the next morning. Now that the 'tropica' has pretty much melted back, the Crypt parva in one section that it was shading is showing melt, too. (We won't even discuss what my Buce in there is doing.) Ack! I knew from past experience, of course, that depriving Crypts of light for a few days would cause that, but increasing it? I read a few articles online about Crypt melt. One of them basically said if you look at it wrong it'll melt. 😆 I'm sure it's not quite THAT bad, but you gotta wonder sometimes.... 😋 1 Link to comment Share on other sites More sharing options...

I was always battling my mum over eating peas, then I started keeping fish and learned peas are given to constipated fish. I could not resist!

zayackylepga Posted December 1, 2021 Author Share Posted December 1, 2021 More leaves melting every day, just going to keep trimming the melted ones off and see what happens. I just put another LED light in the back of the tank so they might not like that change either. Just gonna have them melt and come back I guess. Planning on rescaping next week anyway. Have aquasolum as substrate and want to put a layer of sand on top. Hate trying to plant/put root tabs in, they always end up floating to the top eventually Link to comment Share on other sites More sharing options...

I did not have a german shepherd to eat the peas for me, and if I had forced any of my brothers they would have screamed, resulting in double portions. And they were canned peas, because where I grew up fresh or frozen peas did not exist. 🤮🤢 Good to know you were able to do other things during those decades! 🤪 Edited December 1, 2021 by eatyourpeas 2 Link to comment Share on other sites More sharing options...

If so, have you tried puncturing the capsule with a needle before shoving them under the substrate? It's the air inside that causes floatation. Puncturing the capsule allows the release of air as you shove them in. Edited December 2, 2021 by Dawn T 1 Link to comment Share on other sites More sharing options...

BrycePilaf Posted December 3, 2021 Share Posted December 3, 2021 I don’t have much to add as far as possible reasons for the melting, just that my C. wendtii that I bought 2 months ago from Aquarium Co-op and had been growing great (and never melted after I planted it) decided to melt on me 2 days after a water change. I had also added the tank’s first dose of Easy Green and that might have done it. I’m bummed it’s melted but at least it looked good when the family was here for Thanksgiving. 🙂 Link to comment Share on other sites More sharing options...
