Zapins My gut feeling is it isn't potassium, but the plecos.

I suppose we'll see over the next few weeks as you add potassium.

Newman no i did not remove the plecos.
i can't they are a part of my tank haha.

Zapins Did you remove the plecos?

Also, I think the root tabs you use have potassium in them.

I am interested to see what happens. Post an update when you can, pics would be nice too!

Newman turns out, i was missing Potassium...i checked all my ferts and that was the only missing nutrient - an important one too.
got some today.
swords look horrendous. old leaves are dying, holes, yellow, death, horrible...x_x

potassium deficiency makes sense, I will update on it once it gets going again.

Zapins Yes definitely pleco damage. Even 1 fish can mess up a sword plant quite badly. They are primarily nocturnal so they are likely doing it at night.

I'm not sure about carnivorous plecos, perhaps they do leave plants alone I've never really kept them.
12-04-2013 09:17 PM
Newman dang, you really think so? i only have 3 BN pleco juveniles in here and i was hoping that when i reduced their numbers from 70+ to 3 that the plant eating would stop. i guess not lol. i never see them eating it though so it must be at night.

my other 6 plecos are all carnivorous hypancistrus so they wouldn't touch my plants.
12-04-2013 02:06 PM
Zapins Looks like pleco/catfish damage for sure.

Newman Yeah, leaves arent curling any more - must have been a shipping stress thing as the plants put out only 2-3 curled leaves before putting out good looking ones.

however now my older and even medium-age leaves are starting to get holes in them. it's like the tissue is thinning out and the net venation of the leaf is starting to get holey and the tissue is thinning out until holes appear. am i not fertilizing enough? the oldest leaves are turning yellow which i think may be normal since they are old, but am not sure.

Medium age leaves:

Older leaves:

Normal? Abnormal?

Zapins Any updates on your plants?
11-22-2013 12:13 AM
Newman well hopefully new leaves will not curl as the ones in the photos. it could have been shipping stress.

i dont think my LFS will test the Ca on FW only saltwater. same with Mag.
And i already can measure my GH, i've posted it in an earlier post.

We'll see what happens.

Zapins Hard water is not really a problem. I had well water with 21 degrees of hardness and plants grew amazingly well in that tank. Best plants I've ever grown really.

DI is one way to alter the ratio, but so is adding Ca and stopping any Mg addition. Before you start changing Ca:Mg ratios though, why not take a water sample to the LFS and have them test it for free. Ask them to do a Ca test and a GH test. We can calculate what the Mg is from those two numbers. You may not have a problem with Ca:Mg at all.

Also, the curling you are seeing isn't quite bad enough to really definitively identify it as a deficiency. More time is needed to say for sure.
11-21-2013 04:19 PM
Newman well there is no way to control the two right? buying DI water is not an option - this is meant to be a low cost maintenance tank.
if the mag is coming from the tap then nothing i can do about it. the only way i can control it is limit mag from the Kent fert by dosing less.

I'll just live with the problem i guess. maybe not all leaves will curl.
11-21-2013 03:12 PM
Zapins Give it a bit of time. The issue will probably become more clear with time.

Also, if your Mg level excedes the Ca level you will often see curling. It isn't about ppms it is about the ratio between the two that causes the issue.

Newman i always have osmocote tabs under the plants.

i dose Kent fert like i said which has nitrogen source/nitrates and all the other useful stuff like magnesium, boron, sulfur.

my tank water has no toxic forms of chlorine. i always treat water with prime before putting it into the tank. chlorine is converted to a safer form for fish.

also i am quite high on bioload with fish (mostly plecos) and tons and tons of snails that poop everywhere. so there are lots of phosphates, nitrates, and carbon sources available for the swords. i do not get why they'd be curing. older leaves are not deteriorating yet.
11-21-2013 05:01 AM
Zapins Curling can be due to a lot of things. It could be an imbalance of Ca:Mg (too high Mg). Chlorine from untreated water can cause curling, nitrate deficiency can cause curling and deterioration in older leaves possibly a few other things.

Did you manage to get any root tabs for the new plants?

What are you adding for nitrates currently?
