This plant can be a saviour. It secretes antibiotic substances which can help to prevent cyanobacteria (the blue-green algae). This fact alone makes it a must have plant.

The negatives of including Egeria Densa are that (1) It will grow extremely long regardless of tank dimensions (like the onion plant), then it can hog the tank's light for other plants as it spreads itself across the surface; (2) It can become a collection point for fish faeces and other undesirable deposits over time, this can discolour the plant if not removed. Otherwise it is a good fast growing beautiful plant.

I am new to aquariums and I just got these because they were US$1.50 at the store for a bunch. Unfortunately, they had snails, but nothing a quick bleach dip couldn't take care of. I let them float at the top of my small Eclipse 25 L and they grew like crazy. Not to mention that my goldfish loved them. I transplanted the clippings to my 115 L and they are doing great! No CO2, no fertilizer. I just wish they would stay in the gravel better...they seem to float off every once in awhile.

Great plant. Tends to grow thin and strappy if not given sufficient light. Grows in almost any condition, and provides good cover for fry. Delicious to fish such as goldfish, and to humans. I tried some!

I didn't have a fluorescent light on my tank for about 4 months and this amazing plant was able to grow with a normal 60 Watts incandescent bulb. I love it, and it became even better when I used the adequate lighting, so I guess it can handle not so bright light as well.

This plant is a favorite of herbivorous fish that just love to nibble at the green leaves, especially with my goldfish that quickly decided it was an ideal breakfast bar. Make sure to secure it into the substrate because it tends to escape and float around.

This plant has become nothing but a nuisance in my tank, due to its hardiness and rapid growth rate. Under 110 W of light, moderate CO2 injection through electrolysis, and light fertilization, each stem of this plant will double in length in about 10 days. I try to keep a small amount, however if it is not tended to frequently, it will quickly cover the top of my tank blocking light from other smaller plants. I do recommend this plant though, to those who need a quick filler for bare areas in their tank.

Simply put, any aquarist should have Egeria in their tank if they can get hold of it. Not only is it nice for the fish, but it is the ultimate nitrate vacuum. My tap water has 10 ppm nitrates, but my 95 liter tank's water has remained steady at 0 ppm nitrates for eight months now, with four bunches. My water is crystal clear with very little algae. It does require maintenance, I admit - mine doubles in size every fortnight. I haven't even bothered to plant it - I keep it in bunches, and every two weeks I take the bunches out, chop off the bottom half, rebundle it and place it back in. I've grown it under 0.4 W/L lighting and no CO2, and also 0.6 W/L lighting with CO2. I consider this plant the last stage in my biological filtration system. I put in fish food; I remove plant. One word of warning, though: do NOT throw this plant into outside ponds or lakes, it is horribly invasive.

I bought 2 bunches of this miraculous plant for my 180 litre community. It is growing like crazy! I bought it at half this height, and now if it continues to grow at this speed it will be at the top of the aquarium before the month is out. I use aquarium fertilizer with every water change, and the plant is un-bunched and rooted in the gravel.
