Aquatic fertilizer?
I have an amazon sword, anubias, java fern and african fern in a 26 gallon
tank with a 15watt fluorescent light. Everything other than the anubias is getting yellow leaves (old ones) and holes are appearing in the leaves as well. I know I don't have that much light but i get a lot of non direct light through the windows during the day. I'm thinking fish food might not be enough fertilizer for the plants. What's recommended to fertilize aquatic plants? Is there a liquid I can add to the water, or something i can stick in the gravel near the roots? Any suggestions would be appreciated. -Iman |

Yellowing can also be a sign of low Potassium and iron levels. Java fern and
Swords have leaves that die after a certain period of time too. The anubias leaves last much longer. Some of what you are seeing could be natural die back. If you are getting new growth from the middle of the sword plant that isn't yellow, then it is most likely that you have old leaves coming to the end of their life span. This can be frustrating for newbies, they buy a nice plant and it looks good in their tank for a month or two but it doesn't get enough light or nutrients to grow new leaves to replace the old, and the plant slowly dies. 15 watts of light is on the low side for swords to grow well, so it may be doomed to a slow death or will shrink in size until it is hardly noticeable. The java fern and the anubias are low light plants that can almost be grown in the dark. "Iman Mostafavi" wrote in message . ..

I have the same problem with my amazon sword. My light is 15 watt in 20
gallon about same as yours. I have tried the root tables, jobes sticks and seachem flourish fert and they dont seem to help the swords much. I also have DIY CO2 running and do water change every 10 days. Other plants ,java fern and anubius are doing great. My next option is to increase the lighting to 30 watt. Hopefully this is what the sword needs. I also had rotala indica in tank and it has slowly died. Please post me if you can get your sword growing again. "rnj" wrote in message ...

Hi there,
Here are my thoughts: 1. You probably need more light. At a minimum you'll need 2-3 watts per gallon. I'd say that is major drawback on plant growth. 2. You might consider CO2. A homemade set up can easily be made with some pop bottles, sugar, and yeast. The results are dramatic. Your plants and fish will be much happier. Mike "Iman Mostafavi" wrote in message . ..
