    Good idea or bad?

    I just bought a replacement dual-bulb Glo T5 light assembly that came with bulbs...I already had a 10000k, 8700k and a ColorMax (all CoralLife). The new bulbs are a “black light” and a “day light” bulb...the former says Glo on it but otherwise there are no discenerable markings.

    I have a freshwater tank, 55gal, planted with Jungle Val, duckweed, hornwort, hygrophila polysperma, baby crypt wendtii. I like the look of the new bulbs but wondering if it’s not a good combo for these plants since it seems more designed for saltwater and maybe coral.

    Thanks in advance...

    these aren't the best suited for your planted aquarium. that number you gave is in corespondance with the color light. Normally, for a planted aquarium; you want a bulb arond 7,000k.
