    Anyone can share the correct lights to use for a 2.5 feet tank. I'm currently using 3 18 WATTS FL lights. Don't think its enough. Plants are not photosynthesizing.
    Planing to buy PL but dont know whether they have for 2.5 feet tanks.

    Call and check with Nature Aquarium. See LFS list, link at top of page.
    Vincent - AQ is for everyone, but not for 'u' and 'mi'.
    Why use punctuation? See what a difference it makes:
    A woman, without her man, is nothing.
    A woman: without her, man is nothing.

    you can use the tank calculator in AQ to calculator the amount of light required for your tank

    3x 18W is sufficient if you plan to have a low-light setup. Unless your plants are dying, chances are that they are actually doing ok. Pearling (which is what I think you are looking for) is what you observe when the O2 in the water column is saturated. For that, you will need to have strong lighting, CO2 injection and proper fertilization.

    I was using 3 x 18w for my 2.5ft tanks for few years. Not much problem but some plants cannot grew nicely. For your case, plants not photosynthesizing is probably due to co2 or nutrient. If you go to NA, he will probably sell you the 2 x 36 PL lights which is also not enought! (IMO)

    Thanks

    Thanks everyone who replied. Plants are growing except for pearling effect. However managed to add some neon tetras wihout dying. Algae started growing a few days ago. decided to see wat happens.
    As for the PL lights, too expensive. Found out they cost 90 plus! way above my budget. haha... So i'll stick to FL lights for now! haha!
