    Have a couple of red stem plants (rotala rotundifolia/ludwigia repens) that actually grow green in my tank. Not sure why.

    Follows the tank data:

    20 Gallon (60 x 35 x 38cm)
    72W T5 with arcadia reflectors (bulbs are 2 months old)
    Pressurized CO2 (3 bubbles per second)
    9h photoperiod
    PH 6
    GH 3
    KH near zero

    Daily dosing:

    5mls TMG
    6mls seachem iron
    6ppm potassium
    1ppm phosphate

    Do not dose nitrate, as there is always around 5ppm NO3 available.

    possible to raise the water hardness up to at least GH6 or more if you wan to keep red plants (without other plants which require softer water)?

    do not use red spectrum peak bulb. Must have some blue in peak spectrum in your bulb.
