    Left in the dark


    It seems today that the ballast for my Power Compact lights has decided to no longer work. The problem is, the only light I now have for my tank is my old 20 watt powerGlo flourescent light. I dont have any corals yet, but will my other critters be alright with the reduced light intensity and no actinics for a little while? I have:

    1 Tomato Clown
    1 Mandarin Goby
    1 Lawnmower Blenny
    1 Pepermint Shrimp
    Blue legged hermit crab

    What sorts of negative side effects can I expect due to the decreased light intensity?


    27 Gallon Saltwater tank, 110W PC Light, Seaclone 100, 5 gallon HOB Fuge,Approx. 30lbs Live rock, Aragamax sand substrate.
    Tomato clown, Mandarin dragonnet, Bicolor Angel, Assorted hermits and snails, Cleaner Shrimp.
    Assorted mushrooms, Zoanthids, Finger Leather.

    If no algae grows those critters who eat algae might start getting hungry.

    Otherwise, fish and invertibrates don't need light beyond enough to see where they are swimming / walking / oozing.

    You won't want to leave it in the dark for very long (weeks to months), but, don't panic while you get your lights going again.

    Bad Lighting = Algea in my experience. i would think your fish will be fine though for a little while!

    Why is it called "cargo" when it goes by ship, and "shipment" when it goes by car?

    Your critters will be fine for a while. Corraline might take a small hit but it will recover.
