One of the things I have tried to do as I progress in this hobby is to look for the most obvious solution to a problem. I remember once calling my ISP regarding a problem I had connecting to the NET. The problem was solved when I discovered my parrot had chewed through a cable.

I have a 50 gallon co2 tank up for about 6 weeks. My dwarf saggitaria is growing in very pale and seems to show signs of fe deficiency. I am doing EI dosing and have a drop checker with a kh reference solution made with baking soda and distilled water. I added iron - no help.

For now I won't get into all the parameters of my tank other than to say I have a reasonable level of confidence that my light, co2, and nutrient levels are ok.

Tonight I stood back and while trying to come up with some exotic explanation of the problem, I noticed that the saggitaria plants seemed to be planted a little deep with the crown a little below the surface. So I went in and pulled them up a bit.

Could something this simple be the cause of what appeared to be a nutrient problem ?

True, many times such simple issues often we overlook
I do not think that is the case here.

Sometimes tap water changes can mess with folks.
They add more Chlorine or Copper or etc.....
Or someone uses well water with high Na+ etc.

Some plants might need some adaptation, but you should see signs of decent growth within 1 week for most plants and a good eye can see the change in growth in a few hours/1 day.

Paleness can stem from many issues.
Post a picture might help.

I am having a similiar problem with my dwarf sags as well.

My vals have shot out tons of new sprouts, my ozelot swords are growing many new healthy looking leaves and my pennywort and assorted stem plants are flourishing. However, my dwarf sags have started to turn a yellow and I only have two of them producing shoots. The only other plant that I may be having issues with is my crypt lucens which appears to be turning yellow as well (this may just be the color as crypts change in different tanks and the leaves feel sturdy), and an aquarium lily that was damaged in shipment and now all I have is a bulb that likes to grow algae. I thought a nutrient deficiency would show up on my stem plants first since they grow faster. Is this a wrong assumption?

I thought it may be light since my dwarf sags are well dwarf but my lower portions on my stem plants are still thriving, and my new val sprouts are growing well also.

I have only been set up for two weeks but all my other plants seem to be thriving and I heard dwarf sag can almost be invasive it grows so fast.

Any ideas? Are Dwarf sags more sensitive to anything? I'm not at home otherwise I would post a photo.

All I have outside of plant life is a bulldog pleco, 6 amano shrimp and I just added 9 danios yesterday. I'm waiting on my LFS to get some oto's.

I am running a low tech no co2 no excel 75 gallon.
Lighting is 4 40 watt t-12's 6700K
I dose per the non co2 methods article with the exact products mentioned.
I only top off evaporated water which is about 5 gallons a week or just under.
I use Seachem prime as a water conditioner and probably overdose a little since I only treat 5 gallons at a time.

It's interesting you have a similar problem. Although my sags are growing in pale, I am actually seeing quite a bit of growth. I do have some sag in my low tech non co2 tank and they seem fine. I just ordered a digital camera which I will have next week. I will plan to poat a photo as soon as I figure out how to use my new toy.


Henry

Well not sure if I posted it right but heres one of my dwarf subulata any ideas what I'm missing or what is wrong? Is it an Iron deficiency and if so what besides equilibrium can I dose to help.

To me that has inadequate CO2 written all over it.

If you do EI for a week or two, that will rule out the nutrients, then you just have CO2 to contend with.

If new growth is small, shortened etc, melting , it's very likely CO2.
If you use EI, always look there first if there's algae or other issues, you can always do a mid week water change and more than 50% if you suspect anything and reset the tank.

Then check the CO2 carefully.
Excess CO2 will never hurt the plants, it'll just gas the fish.
So if the plants are hurting, most often it's due to the CO2.

Tom,

I was trying to do a non co2 tank and I dose ferts so it is likely the co2. How then would I fix this? Is this a middle stage I have to deal with until the plants adapt or should I tone down my light wattage to try to match the co2 uptake? Growth rate is unimportant to me. Healthy plants is ;-)

My ozelot sword, rotala indica, pennywort, are all doing well and growing pretty quickly. I just put a Ludwigia repens in there and it seems happy. I can't tell if the Ludwigia has grown as it is pretty large to begin with, but theres no loss of leaves or coloring.

My val spiralis is producing new plants quickly(I had 20 I bet I have 40 or so now) and growth is good however the longer leaves turn brown at the tip and melt. Those were on the plant prior to my aquarium so I chalked that up to adapting to my tank.

I did have some brown algae and some green algae of some sort on my anubias nana but I moved it closer to my stems and I woke up this morning and it was gone ;-) I have a little bit of brown algae on some of my other plants but I heard this sometimes is common in new tanks. I've got 6 amano shrimp that seem to keep most other algae at bay. I have some fuzz algae on my plants but it comes and goes as the shrimp snack on it. I plan on getting about 5 or 6 ottos as soon as I can find them around me and some more shrimp when my LFS restocks. There is no algae on my glass or the substrate.

The only other thing in my tank that i have a question about is a dwarf aquarium lily bulb. The plant died in shipping but I planted the bulb anyway. It now get a bluish white fuzz on it and only it. I thought it was BGA. No new growth. I tried to pull it out and wash it a couple days ago but it grew right back. Also, the bulb stinks!! Is it dead? Should I just toss it?

The tip of the leaf looks like it was physically damaged in some way, perhaps by being exposed to air or by contacting a hot light. The line of demarcation between dark and green seems too sharp for it to have been caused by a nutrient deficiency. Also, there don't seem to be similar areas on the other plants.

Bill

Lack of CO2 can cause exactly that look, its a common sight on java fern in bad CO2 conditions.



Crazy-

If your light is highish, and trying to drive fast growth, and your dosing nutrients, then it has to be CO2.. if you want to do a non-co2 tank, then turn down the lighting and switch to a light dosing schedule. The problems arise when we try to do something in the middle. Good light with no Co2 = nightmares on a stick.
