AS would do it. Imagine how you get 4+ppm ammonia in a 60+g tank. Now realize how you have maybe a cup of water solvating almost the same amount of ammonia. Until bacteria starts to digest some of the ammonia expect to see some problems.

Mold in some respects is good. It is accelerating the natural decomposition of organic matter. However it can also kill your plants.

If it is on driftwood and I wash it off into the plants (but it doesn't grow) can it hurt the plants?

Day 7 of DSM for my HC, and unsure of the results so far.

I pretty positive there is some new growth going on but it sure is slow progress.

As you can see in the pictures below some look completely melted while the one seems to have new growth. The last picture is just blurry :bounce: BUT its nice and green and there are some patches still remaining that way.

Im using ADA 60P with ADA soil, and Fugeray planted plus with blue red, and white lights on for about 13 hours a day. I've been misting once or every other day and opening the plastic wrap once or every other day to let air exchange.

Looks like you're doing good & your through the worst of it. With these things a lot of times I find it looks worse before it gets better

Are there small spider-web like threads in your HC near the damaged area?

They should look like this:

It is difficult to see from the photos above because they are a little blurry but what might have happened is your HC may have been originally grown submersed, then a few leaves dried out when they were emersed, then a fungus attacked some of them a little later on when the enclosure got too wet.

Have a look at this guy's pictures and then look at my reply on the second page, does any of that apply to you?

This scenario sounds a lot like what I've always known to be called pithium in the horticulture world, is it the same in the aquatic plant realm?

Seadon, yes it sounds very similar to pythium. I do not know if it is a species of pythium causing the rot, but it seems highly likely. They both thrive in the same conditions (wet soil).

Here are some photos I took of the fungus attacking HC, it seems to actually invade the root/stem/leaves and digests tissue from the inside out.

 

[AquaPlants]

Very interesting stuff! I haven't seen any web like fungas on the hc but also did not know to look for it. I will check now I know what to look for when I get home from work tonight.

I also noticed my hc isn't near as wet as the one in the photo.

I'll try and take better photos later and repost.

Thanks

Hey same, mine are pretty much dead and it is day 7. ^_^

I tried to get better pictures of the plants up close but can't seem to get them to be clear enough.

I am not finding any web like stuff growing on or near the HC. Is Necrosis always visible in web like form?

I noticed I do have some growth coming. I think I have a few patches that are completely dead.. Like 3 or 4 of them. Ill wait it out for another week and see what happens.

I am also spraying with carbon excel diluted with DI water. I wonder what would happen if I sprayed peroxide on the plant?

 

[Zapins]

If the problem you have is fungus then you'll see the webs. If it is a different problem then you won't. They can be easy to overlook unless you have bright light and happen to see if fro the right angle.

Your HC might just have dried out a bit if it was originally submersed. If you see new growth then your plants will likely recover and keep growing.

I would try misting a 3% hydro peroxide solution

Yes I pulled 2 small patches that appear to have NO GREEN at all in it. I observed it and found nothing as for as webs go. the roots were white and even grown down into the substrate... I think I just wasted 2 patches lol.

So you guys think peroxide would prevent fungus from growing?

 

[Zapins]

No, the fungus burrows into plant tissue which would shield it from peroxide. If it is fungus then you either dry the setup out a bit or completely submerse the tank and drown the fungus out.

The webs aren't visible in the highly decayed parts, they are visible in the browning areas that still have normal leaf shape.

 

[AquaPlants]

Ok cool! I never had browning appear in the tank. It just went dry and scaly at first then a bit translucent then died. Kinda looked like a plant starving for water and I'm hoping that's all it was!

Will excel help prevent fungus?

 

[Seadon]

Will excel help prevent fungus?

I would say in and of itself, no...but with a little time it may help the plants get a little stronger and healthier, helping them fight it off on their own better.

HC is definitely getting new growth! I see little sprouts coming out over the dead patches and the other healthier patches. This is 9th day in I believe. Ill post pics next Saturday to show how much progress.

A little late for you now but could help you or some one else down the line.

Ok, so the exact situation you are going through happened to me OP. The fundamental cause was that the humidity was way too high in my tank and it encouraged mold to grow while the plant was weakened and rotted. This is why the leaves get transparent. Flood your tank for about 3 days and then drain. Invest in a cheap hygrometer and don't the humidity exceed 85%. Personally, I failed dry start twice and I am done with HC. Ironically, my HC takes off only after I flood the tank and start my CO2/ferts. One of the members here showed me this video as proof that too much humidity will melt HC.

It is a fungus that attacks HC when it is too damp. You can see the thread like filaments in this photo and read more about it here:
