How do I get fuller growth on Egeria densa?
Hi,
I picked up some Egeria densa last week. I have had good luck with this plant before and I found a sample for sale that looked very healthy and dense. I know that this plant grows very quickly and that seems to be the case in my tank. But, the new growth is not nearly as full or dense as the existing plant growth. It appears more stringy (more space between new leaves) than the thick dense older growth. I have a 46 gallon tank. I have plenty of light, 4 wpg @ 12hrs a day. I am using DIY CO2, about 20ppm Supplementing with Seachem Flourish every other day, 1mL every 48 hrs. I can give more info tomorrow if needed, I will run my other test tonight. My thoughts are that it is not getting enough nutrients, but I would have thought that my supplement would have helped. Could it be that this plant would grow denser in a low light environment? It seems like it is growing so fast that it doesn't give itself a chance to get dense. Thanks, Tony |

How do I get fuller growth on Egeria densa?
And doesn't spectrum has something to with it as well? If the light is too
blue, the stem plant is taller, if it is too red it becomes smaller and bushier (?) "Tony" wrote in message om... Hi, I picked up some Egeria densa last week.

How do I get fuller growth on Egeria densa?
The water temperature is a concern, but in your case I think it's the
lighting. I have had this plant from time to time and always get the same results. I have slightly over 4 watts per gallon. The plant grows about 3 inches or more a day and is "stringy". My temp. is in the mid to upper 70's. The plant does really well, but the length between leaves is great. I'm guessing your Egeria is growing fast, right? -- Craig Brye University of Phoenix Online "Tony" wrote in message om... Hi, I picked up some Egeria densa last week.

How do I get fuller growth on Egeria densa?
mine has dense leave density, but the leaves itself are daintier, finer, and
the stalk is thinner.... there are a few with more distance between the leaves, but not all are doing that... (one floating on the surface is stringier than the one actually planted into the gravel) it's a moderate lit tank (~1-1.5WPG)... linda "Craig Brye" wrote in message ...

How do I get fuller growth on Egeria densa?
I talked to my LFS guy. I told him that the new plant growth wasn't
as thick as the old plant that I bought. He said that the Egeria densa that I bought was grown in Florida, outside, in very nutrient rich water. It also grows in very dense groups, meaning that the individual stems are very close together. They are then harvested by cutting off the tops of the plant. These plants receive natural light, probably in shallow water. I'm not sure how exactly I can re-create that. These plants may have been growing slowly considering it is now March and these plants were probably harvested some time around February. In outdoor conditions that would mean that light was not at its peak and the plants probably grew slower and more dense. In addition the water temp was probably at its lowest for the year, also meaning slow growth. Finally, the water that they grew in was probably a lot more nutrient rich than my water. I can probably increase some of the nutrients in my tank, but probably not to the level that they orginally grew in. From what I was told, the environment like a muddy river. I could probably just drop some laterite in my tank to make it look like that, but it still wouldn't be the same. This might also mean that the plants are only getting light from the top. This could make their leaves fuller. One of the few things that I am going to try it to grow the plants very tightly packed. I have been replanting the new growth within the same area. Hopefully this will cause the plant to try and grow fuller and not just taller. It doesn't seem to make sense, but it is worth a shot. I've been considering doing an experiment in a bucket in the basement where it is cooler and I can control the light more. I was thinking that I might make the water super rich, and do the same for the substrate. My basement is much cooler right now and then I can change the amount of lighting to see if it makes a difference. If that doesn't work, I can change the temp. We'll have to see about that experiment, no promises. Let me know if you draw different conclusions that I did. As I side note, my Echinodorus cordifolius that is growing next to the Egeria densa does not have any black or brown algae growing on the new leaves. The Egeria densa seems to be pulling a lot of the nitrates out of the tank, which is what I wanted with my goldfish. I had nitrates over 40 ppm and now it is down to 10-20 ppm. |
