    Looking for opinions on running a longer photo period over the weekend.

    Stats:
    26 gal
    65w Coralife PC
    medium to heavy planted
    CO2 at approx 30ppm
    EI dosing - Macros 3x/week, Micros 3X Week
    N - 1/4tsp
    P - 1/16tsp
    K - 1/16tsp
    CSM +B - 4ml solution (1 TBSP to 1 cup H20)
    Flourish Iron - 2ml after 50% H20 change
    Flourish - 2ml after 50% H20 change
    Excel - 2ml 2X Week

    Weekday lighting - On at noon off at 8:30pm (8.5Hrs)
    Friday - On at Noon of at 10pm (10 Hrs)
    Sat - On at 8am off at 10pm (14 hrs)
    Sun - On at 8am off at 8pm (12 hrs)

    The only reason for the change from weekday schedule is to allow more viewing time during the weekend.

    Could I run into excessive lighting issues, algae, etc by running the lights longer a couple days a week?

    Thanks,
    Mike

    I do this on my marine tank with macroalgae without any ill effect, although my 'extended periods' are still shorter than yours (about 12.5 hours Sat & Sun, normal 8hrs on Friday).

    I do not think it'll do too much.
