which is rotting exactly?
Cryptocoryne, glosso or ludwiga?
Hi guys,
I'm new here. Wondering if you guys can figure out this problem. I'm having this rot on my glossos and ludwigia arcuata for some time already, like 4 months. Made a search and find out probably due to excess nitrate. Did try combating with water changes 50% of the 2fter weekly and trimming the affected leaves. But doesn't seems to help much. Also did a nitrate test, readings at 5 ~ 10 ppm.
What could be affecting it? BTW lighting at 72W.
Everything should be made as simple as possible...but not one bit simpler.

I don't think your NO3 level is excessive. Lighting is fine too. Glosso for one is a hungry nutrient feeder. Is your CO2 level sufficient? How about base and liquid fert?
The rot is called crytocoryne rot. Its starts up with tiny holes at the margins of the leaves glosso and the ludwigia. It will slowly spread till all the leave rot. Hope this will clearifies you. Thanks.

Pssst... Crytocorynes are plants. Cryptocoryne Rot refers to the tendency for these plants to almost completedly melt away due to changes in water conditions and then grow back again.
Checked your PO4 levels? Are you fertilising? CO2? I concur with Budak, your NO3 levels are fine.

Yup I know crpto are plants. Just so happens it has the same name as the rot. Ok. Thanks. I will go check the PO4 level. CO2 running at 1-2 bps and with dennerle base fert. Dosing Florish/Florish Iron every 3 days.

Hey..me no crypt expert but I think crypt rot will happened due to water condition but the crypt will make a comeback by growing new leaves which in my opinion look more olive-intensive in colour.. Crypt rot is normal? Happened every crypt that I introduced to the tank...

erm... maybe I'm blind or super blur, but what did you say your tank size was ? I am guessing maybe light not enough...

unlike German measles, which also infects non-Teutons, crypt rot only affects crypts, but the rhizomes will regrow new foliage if left alone. For stem plants, such rot usually signals a severe deficiency of some vital nutrient. Can you test your pH and KH to get a CO2 level reading? 1-2 bps doesn't indicate much. What about other plants/fish in the tank?
i only thought of one thing
what base fert are you using, if any?
Taz, I get what you mean now, but the term crypt rot is only applied to crypts (as Bubak stated). Using the term "crypt rot", you're only cofusing ppl.

ok sorry about that. I made a search and the description fits my situation. BTW the pH about 6.8 ~ 7.0 with kh 5. Using stick test Pharmaceutical aquarium brand I think.

What's the temp like? The crypts are melting is probably due to water condition change (as mention b4). It should sprout out new shoots soon.
Other reasons could be due to the plant you planted was an emerse form and they are converting to submerse form.
More info will be appreciated.
also if u have shifted ur cryto.. mostly likely it will rot for the first-two weeks and after it stable down.. it will grow back.. cheers----------------

Er Sherwin and YES, taz is referring to his rotting glosso and ludwigia, not cryptocoryne.
He used "cryptocoryne rot" because he thought that condition applies to his plants.
Jason (wks),
You're rite..... ok.... what's the temp anayway. Did the plants grew at all or it melted after you planted it?
High nitrates level causes plant rot..like in my case..the MMs all melted away...

Wynx, how high was your nitrate?
I can have only experience as high as 40ppm without problem. My NO3 have not gone over that.
I find that plants suck up N really fast. It is not so common in a well planted tank to have NO3 much higher. It could be due to other limitations which cause the plants to stunt resulting the buildup of NO3.
Just curious.

Taz,
how big is your tank? typically I only encountered stem rot under situations of insufficient light, nutrient deficiencies, or overpruning...
Wynx,
I'm not sure where you got the info about NO3 causing Rot... could you provide the link? Would like to read up.

Sorry late reply. The tank as mentioned is 2ft. The glosso is rotting at the leaves. Only the older one got affected. Even after trimming it, it start again. Nitrate 5 ~ 10ppm. PO4 last measured 0.1ppm. Temp at 28~29deg. I now suspect is the spotted algae on the leaves that causes it. But is it possible?
Regards.
