Carpet grassses

[Mash]

I have a planted tank but am relatively new to aquariums. Want I really want is a short grass to carpet part of my tank, about 40 gallons, but have no idea which is best. None of my local shops know or have any.

I think what you are looking for is dwarf hair grass. It looks great, but requires highlight and co2 or high dose glut.

My lighting is about 2 watts per litre and what is glut?

Do you mean Glutaraldehyde by glut? Is there any shorter plants or do you just need to keep cutting as necessary?

 

[flitabout]

Well the watts per gallon depends on a couple things. Like depth and type of bulb. The watts per gallon, rule doesn't quite apply to t5ho because the lighting is so intense. Depth is a factor because the shorter the tank the more intensity reaches the substrate.
What type of lamps do you have, and what is the spectrum or the k rating? Yes glut is Glutaraldehyde. Also the higher the light the shorter the plants. I have had dhg in 1 of my tanks for 4 months now and it might be 2 inches tall but it has been carpeting like mad. I haven't had to trim it at all.

I have T5 tubes 45w one day and one natural. I think the spectrum is 895mm? My tanks a Rio 180.
