4x2x2 , 120 gallon. lighting fixture is 8 cm above the tank.

using 2x54W t5ho with parabolic reflector for each tube. D&D giesemann powerchrome and midday. trying to carpet dwarf hairgrass. Am using pressurized co2 too. is the lighting enough ? or do i have to add 1 or 2 more tube ?

It depend on what kind of plants you are keeping.
With the depth of two feet,light penetration to the base might not be sufficient.
So i my advise is you need to plan what kind of plants you are keeping.

hii. my main priority now is to carpet the tank with dhg. I've read that dhg requires high light to carpet ? If not it will grow vertically instead of horizontally

[Evilsands]

2x54W will be <1watt/gallon
(low lighting)

I dont have nice experience with HG,
but my 4ft using 4x54w for my HC, just to make sure they grow horizontally

seems like i have to get another 2 tube then

Your individual parabolic reflector might giving a good PAR value, it depends on its material quality. 2 bulbs are giving good spread for 8 cm above the tank.

Although Mine is 4 bulbs, 11 inches from water surface. Success to make glosso pearling

For Dwarft hair grass,lighting is usually from medium to high lights.
here are a few links that you can refer..

im not sure of the quality from my parabolic reflector though. will just get another 2 tube more to see if theres improvement

Agree. 2 tubes is not enough for sure for the plants that you have on mind. At least 2 more tubes will be needed and remember to change the tube every 6-9months.
