my vallis is dying

[gregorsamsa]

Guys

my tank is 2 x 1 x 1.5
im using a 30 watts fluro tubes
Angelstar Gravel
No ferti base
using tablet Co2 (potpoise brand)
using Plant Plus

my question is, though i on the light for close to 10 hrs, i do not see bubbling.
is it because im using FL? but i do know that 30W is recommended for my set up (50liters)

Also my Valis is slowly dying, there is loss of the green pigment. What is the cause? Because of this i bought Sera iron tablets.

Can help me out? or do i need to get new lights?

30W for a 2ft tank is on the low side. my 1.5ft tank is already using 36W lightings. talk about 2ft. do check your nutrients level and also co2. if its the leaves that are turning transparent and pale, it may be due to iron def.

2 possible causes - CO2 tablets not providing sufficient CO2 and/or your plants is short on macro-nutrients.
