    Dear all,

    I am very confused about the led lightning information on the internet and would like a help from you. I have a 24” depth freshwater aquarium and would like to add a led system for medium or high lighting plants. I have discus fishes and low lighting plants working fine.

    To my knowledge I have two commercial affordable options:
    1) Marineland Double Bright 36” – that seems to not have enough PAR for medium light plants in such deep aquarium (36 – 48” - (16) 1W 6000K White & (8) .06W Blue LEDs 1200 Lumens) (Our Products)

    2) Marineland Reef capable 36” - that seems to have enough PAR readings for this deep, but 10.000 k white leds (36 – 48” - (36) 10,000K White & (6) 460 nm Blue 1W LEDs - 2610 Lumens) (Our Products)

    a) Can I use the Reef capable for freshwater? Or am I wasting too much kelvins for freshwater plants?
    b) Adding two Marineland Double Bright could I solve the problem of low PAR? http://www.marineland.com/uploadedFiles/Marineland/11078iMLLEDCharts.pdf
    c) Actually how much PAR should I have at the bottom for medium/high lighting plants?
    d) DIY system could save more than 50% or solve problems that these commercial options can’t solve?
    e) Do you have any other recommendations or right questions?

    Thanks very much,

    Aquarium specification:

    83 gal

    honestly neither of those are the right spectrum for plants, although they probably will grow some plants.

    I would probably get a 4 bulb t5HO or even a 6 bulb fixture since you have CO2.
