Shriraj IMO for MH lightning 1.5 watts per gallon would be suitable, for T5 lightning 1.2 watts per gallon and for normal lightning 2 watts per gallon. 
Experts if I am wrong please correct me. |

| Normally for a 2 foot length tank of that height one 75W MH would do wonders! |

You want Ferrari - you go for 2 70 watt MH
You want Lambo - Go for 4.5-5.5 WPG.
Cons - DIY Co2, 1 bubble per second Co2 for saving on Co2, Less water change, No proper dosing, and you get a khatara.
You want khatara - go for 1.5WPG
No cons, its already a khatara.
You want Maruti - stay in between.
Cons - a Maruti.
Hope this helps. |

well IMO kelvin should be considered for hieght concerns and not watts.
MH would be great for height 21 but check the kelvins in it , distrubuting into two small MH tubes is advisable rather than on single. Lights are the most complex topic in planted aquarium. |

One of the considerations for lighting is the depth of water column it has to penetrate, for this you have to calculate the height of the substrate and also the height of water level below the surface. So for a 21 Inch height tank as yours if you have 3 Inch Substrate and leave 1 Inch gap on the top. You have 17 Inch Water Column to be penetrated. So IMHO T5HO or PLL Lighting would suffice.
Now for the second part of this puzzle. Just light is not enough, The amount of light also matters. In your case you have planted Glosso and it needs very high light to grow close to the substrate. In low light conditions it starts to grow upwards.
Now for the third and fourth part of the puzzle. If you hit high light you will need to provide good amount of CO2 and Nutrient as well.
A Planted Tank to do well needs Light + CO2 + Nutrients (Substrate&Water) in the right balance, IF either of these parameters go high or low compared to the others , THEN you will have algae issues.
Read Up ......... Read Up .......... Read Up ......... and then decide what setup to do based on what your budget permits. |

@Sushant
Tell us more about your experience with LEDs. Show us some of y our tank pics. Tell us where you bought them, better if you take a pic of your light setup and post it here. Will surely help people. What are your LED specifications? |

@Dev: its a DIY LED setup with 30 x 3W LEDs (Chinese). i have been using it for around 7-8 months. initially i tried running them on the DIY current driver but wasn't satisfied with the overall performance because i was unable to find the right value of resistor in market so switched to a buckpuck. Here are some pics:
pics
these pics where taken just after i tried Aquascaping. this might not be a good aquascape and lacks few basics like dual focal point but its much better than the wild and untidy outgrowth in the past. |

2 Feet long X 1 feet wide. If you get a circular or square reflector the light will spill over / hit the glasses too much on the front and back.
How do you plan to suspend the MH fitting over the tank? They are generally pretty heavy {as opposed to the PLL/T5/T8 fittings} |

@Sushant,
Your tank looks good. Seriously. Take good care of it and it will surely make you proud. Sent you a PM regarding the LEDs. Thanks a ton for posting. |
