    refugium lighting

    Hi all i wonder if you good people could help me i have a 24gal D-D nano and in the rear filter compartments (centre one) i have made a refugium that is 100% chaeto at the mo its run by a 9watt tropical bulb (on 24/7)clamped to the outside of the tank from the side you dont see and sounding that is a home made reflector box lined with foil so all the light is reflected in the centre compartment only now this all works perfectly ammonia 0 nitrite 0 nitrate 0 phostate 0 but what i would like to know is on ebay there is a seller selling 3w 5w and 10 watt led bulbs in yellow,white,green and blue with a range in lumar from 200 to 600 so does anyone know is this enought to grow my chaeto because if it is then i can still have the light on the outside but then i can have light shining from the top which would give me a much better growth in chaeto hence top notch water paras

    anyone know? and happy xmas

    refugium lighting

    Tropical bulbs are good for Chaeto.. but I'd cut back the lighting to give at least two hours of darkness to benefit the little critters that grow amongst it.

    I'd remove the foil reflector.. I wouldn't take the risk of a saltwater reaction with the foil causing metals to enter the water. Polished metal reflectors (e.g. for Arcadia or Juwel lights) are cheap enough to cut to size.

    LEDs can be useful.. but you need to find out their PAR rating, or work it out for yourself from the wavelength of the individual LEDs. To be honest.. you'll be lucky to find a cheap LED with anything like a useful output for supporting photosynthesis.

    The Arcpod 9W/11W are generally recomended for this purpose.. they're splashproof, come with a suitable tropical bulb, clamp to the side and have an in-built reflector.


    Oh.. and..

    this all works perfectly ammonia 0 nitrite 0 nitrate 0 phostate 0

    If it ain't broke.. don't fix it.. (and LEDs are very unlikely to give better algae growth).. and how much more "top notch" do you plan on getting the water? <^EDIT^>

    refugium lighting

    Hi Alastair thanks for the reply i know what your sayin its just although my water is good i still get little stubbon spots of hair algae appear on my rocks that dont really get larger but when i trim them back they still grow so im thinking go the extra hog on the cheato lighting and maybe i can finish the hair algae once and for all and also try to save a bit o cash as the lamps only last 6-9 months but led last 5-10 years (so i heard)
    As for the tin foil backing its not in the tank as what i have done is took off the plastic sticker at the rear of the tank glass so it exposes the centre chamber then built a box (lined with foil)round this and put a solaris 9w light in the box so everything is out side the tank with no possible risk to the water

    cheers
    chopchop and have a happy xmas
