Monster Fish Crypts will do fine with Excel if they're already used to it and you keep up with regular dosing. However, adding Excel for the first time to a tank full of established crypts will result in some melting.

JMN16150 My pondeteriifolia doesn't mind the glutahy-whatchamacallit? It creates new leaves on a regular basis

philipraposo1982 Some people report the same while others report negative effects from excel. The point is that it can harm the plant.

Not something I would risk in my tank, but to each their own.

AquaAurora I've grown crypt wendtii and parva with Seachem Excel and never had an issue.

philipraposo1982 With very hard water your pontederiifolia would be doing great. Even more so with the co2. I am aware that crypts dont like excel though, so I would stop dosing that. There really is no need for excel if you have a pressurized system.

Until my most recent rescape 1 week again I had a problem with acidic water because of safe t sorb substrate. Was a mess for my hard water crypts. I only just realized this recently which is why for a year I continued to deal with crypts that didn't thrive like I know they can.

I don't run co2 or excel. I have a 75g with a planted plus suspending 24" ish above the substrate. PH is 7.6 ish and temp is 77. I switched to pool filter sand substrate with dig root tabs.

Because of the recent rescape all my crypts are going through a melt and all plants are having to readjust to the tank. They were out of water for over 10 hours. So far its not too bad but I have still lost a lot of leaves. A new leaf is on its way for my pontederiifolia so I will take pics and monitor its growth for a while and provide updates.

I am hoping with the acidic water problem being solved I should be able to get decent growth.

Oh and I do a modified dosing, very little potassium and micros with occasional phosphates as needed. I have a heavy fish load so I don't have to worry about nitrates or phosphates generally. I do 2x water changes a week at about 50-60% to keep parameters fro. Fluctuating too much from normal tap water. Less time between WC means less time for things to drastically change.



The first picture is of my smaller plant of the 2. That leaf is older and has yet to melt since the rescape.

The second pic is of the more.matured plant, the new leaf. The rest of the leaves melted and I had to cut them off.

20L all-crypt tank, 30" Planted+, compost/peat moss capped with ecocomplete, very hard water, EI dosing/homemade root tabs (been busy last couple week so haven't been keeping up on this like I should. My crypts are kinda mad at me) and ~16 well-fed white cloud minnows, pressurized CO2 with full recommended dose Excel. How about yourself?

Pontederiifolia that are closest to the light are the most affected, which really makes sense. But even the off-center ones are getting some of that affliction. I've got about 20 different crypt species and Pontederiifolia are the only ones that really look like this. Don't have the time to grab a pic right now unfortunately but can update later.

A few of the parameters will be outdated in a few days though. I just got my Planted+ 24/7 yesterday (LOVE IT!) and am going to tear down and swap the substrate for topsoil with nutricote sprinkled on top and capped with black sand (plus new driftwoood I picked up last week).

Also, to anybody, suggestions about anything else I should consider during my rescape would be super appreciated! It's going down probably this next week, I'm so pumped!

philipraposo1982 Maybe together we can find out what is causing the not so great looking leaves.

I just discovered this post and have been reading through it from the beginning and loving all the great info so far. I only made it to page 13 before I felt the urge to post.

I have been in the hobby for just over a year and more recently been seeking out crpyts as my favourite plant. I my 75g is full of non-stem plants with minimal dosing and no co2 or excel.

Here is my humble collection which will continue to grow.
- Cryptocoryne Aponogetifolia
- Cryptocoryne Cordata 'Grabowski'
- Cryptocoryne Crispatula Balansae
- Cryptocoryne Green Gecko
- Cryptocoryne Parva
- Cryptocoryne Pontederiifolia
- Cryptocoryne Spiralis
- Cryptocoryne Wendtti (Red, Green, Brown)
- Cryptocoryne unknown

My pontederiifolia throws up new leaves regularly but the leaves don't seem to do very well. I only have two of these plants and they are on the small side. The leaves seem to get spots on them. not the typical gsa type of spots but maybe a disease or another type of algae. Black spot? The leaves don't get covered either, and they live for quite a while before really looking bad and I remove it. I really want this plant to thrive as I like it a lot. Anyone have some suggestions?

Here is a pic of the unknown crypt, hopefully someone could give me an idea of what it might be. I understand its difficult to id crypts without a flower but thought I would try.



thanks.
I think the crypt you've got in the picture there is c. walkeri lutea, judging by the bright green/brown color and the upright/kinda slender leaves.

As for your Pontederiifolia, I have the same problem and it's really too bad because other than that it's one of my plants that's doing the best and regularly throws runners.

Nah. It's rather slow growing for me, especially in low tech. It takes months for it to send out a new leaf.

Cryptocoryne pontederiifolia or Cryptocoryne moehlmannii.

AquaAurora Well I'm suffering crypt melt, but I'm 99% sure its because of the spreadable disease 'rhizome rot' often found in anubias. I'd stupidly kept some in a tank with crypts and now they are melting (removed the anubias as soon as I suspected it.. but it was too late...). I've had these crypts since the summer and never had melting issues. Ammonia, nitrite, and nitrates are 0ppm, dosing Seachem:excel, potassium, phosphorus, flourish, iron (and now nitrates), pH is always stable 7.5, hard water, temp 78, low lighting.... Really going to be pissed if I loose all my wendtii and parva... I was going to convert the tank to pure crypt in the spring but no chance of that if the disease is in there ugghh.
