Hairgrass problem

[dannyfish]

Hi all

I facing a problem growing my hairgrass

they are growing but not as bushy as i saw some pic in forum is so bushy and green. I can see runners but also not many.
how to make the plant grow fast / greener / bushy..? i guess somewhere must be wrong...
I don't have any test aids
the only plant that is growing v well is java fern, and the old leave is now covered with new green small plants....1 of the light is becoming transparent which i suspect is too much lighting

My tank

55litres
T5 24W x 4 (4 - 6 hours per day)
DIY Co2 x 3 bottle of 1.5L (Co2 checker show green, i assume is having sufficient co2)
fertilizer is dry dose of CaNo3, K2So4, fleet emena, mg2so4 & CaCo3 & seachem flourish
weekly change of water 20%
temperature 28-30deg (ops)

Any one can assume what is hindering the growth here?
Thank...

My guess is that a lack of stable CO2 is preventing the crazy growth you expect, but it does take a couple months before even eleocharis acicularis to start really taking off.

You have enough light.
You're dosing NKP and micros
You GH/KH is fine

How how long ago did you plant the tank?
Why species of hairgrass is it?
What type of substrate are you using?

A few things:

fast growth isn't necessaarily a good thing.
just because the drop checker is green does not mean you have enough CO2 in the water.

Are you using 4dkh solution in your dropchecker or tank water?

see my edits in the above post. I'd say it takes a good month b4 eleocharis acicularis takes off.
