I bought some the other day from my lfs and it is growing very fast, about two inches in just a few days... however the leaves look like they are disintergrating and turning a bit yellow on some of the plants?

It seems strange to me that it would be growing so well but dieing at the time?

Any ideas?

What temperature water have you get them in? Egeria densa is essentially a cold water plant, so it won`t lookm its best in a tropical set up.

I had some that grew like mad, but it started to get leggy and brown stemmed lower down.

Are you using excel? It don't like excel... I had to cut back on it, because it was melting my egeria.

It in a tropical set up. A couple of the shoots appear to be doing well but some are literally starting to disintergrate.

I use Plant Gro but thats all and I havn't put more in since the densa went in. I think I might throw it out and have a look at a background easy plant to replace it. Im not a huge fan of the way it looks anyway.

My Hyrophila on the ohter hand is brilliant, growing just as fast but nice and bushy !

Mine is growing in 4 different tropical tanks. They range from 72 to 82 degrees. It grows fine for me. (very fast) It is one of my weeds to stop algae. It isn't for looks. I tend to try to hide it in the back behind other plants.

I have taken out the strands that weren't doing so well and kept the good ones. It might have been caused by the planting tightly so I have planted them quite losely, like you say it grows so fast that it is handy to have in the tank!
