Brown Spots on Plant
I recently set up a 20 gallon tank, and added some plants. One of them
developed brown spots on the leaves. You can see the photo at It's planted in the middle of the tank, where there is more light. Could this plant be getting too much light? The other plants, bought at the same time, look great. The disease, whatever it is, seems to be progressing. Is there anything I could do to save this plant? The tank has beed running for two weeks. pH is 7.8, ammonia 0, nitrite 0.25, nitrate 5 ppm. I alwo added some liquid fertilizer. |

I think if you trim the affected leaves (don't worry it will grow back healthy) and place a fertilizer ball under the plant it may solve your problem. I am fairly new to aquatic plants, so I could be wide of the mark, but any way that's what saved any of my plants that this happened to.

The plant is starving to death for sure, but substrate fertilizers, especially one with ammonia are not a good idea.

Those swords are often grown emersed and the foliage doesn't always adapt well to being submerged. If that is the case, healthy new foliage will begin to grow from the middle of the plant. -- __ Elaine T __ __' http://eethomp.com/fish.html '__ |

You know, that pattern of green veins and lighter mesophyl on the older leaves looks EXACTLY like an Echinodorus leaf picture in the Optimum Aquarium (p.117) labeled "Christmas Tree disease." Horst and Kipper say that vein pattern is due to either manganese deficiency or iron overdosing. I see what you mean about the new growth, though. Is that what low nitrogen does? I'm always trying to lower it - not add more. ;-) -- __ Elaine T __ __' http://eethomp.com/fish.html '__ |

leaves looks EXACTLY like an Echinodorus leaf picture in the Optimum Aquarium (p.117) labeled "Christmas Tree disease." Horst and Kipper say that vein pattern is due to either manganese deficiency or iron overdosing. Without doing any tests but in all probability I'd say it's an iron deficiency. Tropica master Grow or SeaChem iron is indicated. Any iron source will do more or less, but these two are IMO the best. I have a slight preference for the Tropica stuff because the bottle is so handy - although you can buy those bottles from GregWatson(.com). I see what you mean about the new growth, though. Is that what low nitrogen does? I'm always trying to lower it - not add more. ;-) Well, there's no hard and fast rule. You have to add enough NO3 to bring you up to where you want to be based on where you are initially. There's a nice graph in that book thatshows the rise in nitrate in German tapwater over time; I have zero nitrate in my well water and would have to add more than somebody who has some in theirs. I aim for 20ppm NO3 and would rather see 30 than 10. -- Need Mercedes parts ? - http://parts.mbz.org http://www.mbz.org | Mercedes Mailing lists: http://lists.mbz.org 633CSi 250SE/C 300SD | Killies, killi.net, Crypts, aquaria.net 1970 280SE, 72 280SE | Old wris****ches http://watches.list.mbz.org |

I just bought some fertilizer pellets, I'll also continue using the liquid
fertilizer. I just don't want to overdose - the label says iron "may be toxic to some fish" - how much of a concern is it? I am new to keeping live plants, and I've never used fertilizer before. |

I've never hurt anything in a tank dosing commercial liquid iron fertilizer by the suggested dosage on the label. -- __ Elaine T __ __' http://eethomp.com/fish.html '__ |
