I have a 30gal with two Aponogeton ulvaceous.Very beautiful plant, but after awhile, the new leaves start looking a little haggard. There are small circular holes on the leaves and brown going down the stems on some of the leaves. It still keeps putting up flower spikes and and new leaves and has tons of roots. What is causing this? Is it the bubble wand behind it or my fish?

Thanks, Theresa

A. ulvaceus is a monster plant. I grew one in my 72 gallon until it dominated the tank and had to be taken out. It only took a month! I have some pics if you're interested in seeing them.

Ulvaceus can be demanding because of its size and very fast growth rate. Do you have any gravel fertilizers under them? On one hand I suggest you put them there; on the other if you do they may grow too fast and large for your tank.
 
So it needs more fertilizer? I give my plants Red Sea's Plant Success Flora Fe and Flora Vit once a week and there is also CO2 injection. Should I use something else?
 
The CO2 injection is good to have. Those fertilizers likely only provide trace nutrients and iron. A. ulvaceus will have high demands for the big 3, N-P-K, Nitrogen, Phosphate, Potassium. Small holes are usually associated with a shortage of Potassium.

I personally use Jobes sticks for lush ferns and palms around big feeders like Aponogetons, Crypts and Sword plants. The sticks are meant for houseplants. They have an N-P-K rating of 16-2-6. They are real cheap at Wal-mart but if you decide to use them, make sure they are well buried in the gravel.
 
So, the sticks won't hurt the fish? That's cool. I will try to find them today. You have been very helpful! Thank you very much! :bowing:
 
No problem, glad to help. They shouldn't hurt the fish as long as they are buried. If you have to pull the plants up, try to vacuum as much of the bits out as you can.

The bigger concern to me is the sticks releasing nutrients in the water and algae using them to grow. If you keep them well buried it shouldn't be a problem though.
 
Well, I found the sticks at Walgreens, of all places. Guess they have a little of everything. So, I buried them at the bottom of the substrate. Now, comes the waiting game....
