5 days and you have green spot already ?

I'm not sure about lighting requirements for 2FT as I've only done <1FT, noticed you are using 24w x 4. Whats your watt per gallon?

As with all planted tanks, you might want to go easy on the bioload within the first few weeks, though your plants mass could help uptake ammonia in your tank, however i've counted like 30+ fishes in your tank ?

no my fish is around 20 of them most very small . the filtration is already matured from my older tank .

Then shouldnt be a problem since its seeded. Might want to check either co2 or lighting/sunlight in that case. I've observed your ADA drop checker showing yellow, should be green for optimal.

so would you advise me to lessen the photo period ? and mind telling me how to calculate the watts per gallon ? im really confused . i know im having 96 watts which is abit much for my tank , as 76 watts should be the optimal for my tank volume .
