    New Scrubber please coment

    Hello,

    My name is Mihai, i found you forum and decided to build a algae scrubber.
    My tank is 200L (52.6 US Gallon), i currently feed approximately 1 cube / day.
    So after my math i came up with:
    Screen 20 x 20 cm (7.8 x 7.8 in), illuminated by 4 x 20w (2 on each side) ( 10cm from screen(4 in)), for the flow i use a Ehaim 1002 (1000l/h - 263 US Gallon/h)(flow its 33.7GPH/inch)

    I have some questions:

    - how many hour of light to use
    - how many cubes i can feed per day (for future use (i have some future big fish (now they are small - 1in)))

    I will come with pictures on my first harvest .

    My today value (Salifert):
    No3 - 15-25
    Po4 - 0.1


    Thank you.

    Welcome.

    1 cube needs 12 square inches with 12 real (not equivalent) fluorescent 2700 or 3000k "warm" or "soft" watts, or 6 LED watts. So yours is good for 4 to 5 cubes, but may not grow much now because it is so big. You can run the light for 8 hours now, and add hours as you add cubes.

    Nice reflectors. If the screen is rough it might be fine the way it is.

    Hello, it is day 3, nothing happen, the screen is the same as i put in, clean white.
    Do you have any recommendation:
    - wait until day 7
    - move the light closer
    - increase the light from 12 to 18 hour
    - on the flow part i cant do nothing - it is at maximum pomp capacity.

    Thank you.

    Wait 14 days.

    The screen looks like cloth.

    Hello, it is not cloth, it is fiber glass used in thermal insulation. it is rough, so algae can stick to it.
    Soon i will order some plastic canvas from ebay.

    It can take weeks to start to grow algae. Be patient. If you have good light and good flow, it will happen.
