Hygrophillia Difformis or Wisteria

[bb]

Hello all,

I've started setting up a new 100 ltr tank. I'm using Eco-Complete as a
substrate and a total of 51w in gro-lux bulbs. I've set up the filter and heater
but not added any fish yet. About two weeks ago I planted three plants I got
mail order from an specialist aqurium plant company. One bunch of Elodea Densa,
Vallisneria Spiralis and a Wisteria. I added 'Leaf Zone' liquid plant feeder as
per instructions.
They all seemed to be doing well and starting to grow. While the other two still
seem okay, today I noticed two things with the Wisteria leaves. While the
Wisteria seems generally healthy the center of one leaf now has a small grey
oval on it. Within the oval the leaf is still there, but it has died and turned
leathery. It looks a bit like sun scorch on a land plant, only the Wisteria
hasn't seen much sun. Also, on another part of the plant, two leaves now have
sooty dark green/black spots on. Can anyone please tell me what is going on, and
what I can do about it?

Thanks.

Hi bb,

I've not seen this on a Hygrophillia myself but I've had a look at my
aquatic plant books and they suggest (rather unhelpfully) that it
could be caused by one of two things - an iron deficiency (which can
be quite common with Hygrophillia since they tend to do well in iron
rich conditions) or some kind of poisoning. With Eco-complete and AP
Leaf Zone I can't see how you could have an iron deficiency and
poisoning seems unlikely if your other plants remain healthy. My only
thought is that it might be some kind of algae? If you have a
microscope perhaps you could take a small sample and have a quick
look? Failing that, is there any way you can post a picture of the
problem you're seeing on the web somewhere?

Sorry not to be more helpful. Hope you find some answers soon.

Hello again,

Thanks for posting the photo. (I know what you mean about getting the
focus right - I struggle with that too!)

>From what I can see there is some yellowing around the spots which
does remind me of iron deficiency. Just to be sure that you've got
enough iron, you could get a small packet of root fertilizer tablets
(I use JBL 7 balls). Any brand will do so long as they're for
aquarium use and have iron in. If you put one of these in the
substrate near the affected plant you could see if it makes a
difference. If there's no improvement at least you can completely
rule out deficiency of iron and trace elements. I'm in two minds
about whether this is worth doing though.

The other thought I had was that this might be some kind of plant
disease - perhaps a fungal problem or even some kind of protozoan. If
it is a disease of some kind I would try to remove as much diseased
tissue as I can without badly damaging the plant.

Best of luck,

Muddy
