    Greetings fellow reefers

    Coralline has finally started growin in my tank but it only growing nicely from the bottom half of my tank, there's also some purple, pink and grey/cream Coralline which looks like mold. Then in some random spots there's green (olive green) Coralline
    My questions r;
    1. Y is the pink and purple CL only growin on the bottom half of my aquarium?

    2. Do u get green and grey/cream CL?

    3. If the answer for question 2 is No, what could it be?

    4. Is there any natural benefit of CL besides adding color?

    Thank is 1m deep with 5x t5s and 2 t8s. Moving about 40x water volume of the DT.

    Hi Kavir
    1. It all depends on the lighting of the system, different colours of Coraline grow at different depths.
    2.Yes you do.
    3.The answer is yes :)
    4.No, it looks good but also eats up your Ca, Mg and Alk.

    Hi Kavir - no REAL benefit to corralline algae, other than providing food to some of the crittters, and also to provide color to the tank.

    Corralline uses up a lot of minerals, from the water, ie. calcium, magnesium, strontium, and others...
    It competes for these minerals, with the corals....

    Corralline also "seals off" LIfe rock....

    So - yes, corralline algae is wanted, and no - it's not ALWAYS good to have a HUGE amount of corralline...

    Corralline algae also indicates that your water parameters is now 100% perfect for keeping corals....

    Different TYPES of corralline, have different colorations. And YES, there can be white/grey/green/beidge corralline algae.....

    The corralline is also dependant on light. Different corralline grows under different light situations....

    Yes - Kavir - it does and can become a problem for the bacteria colonies. That's why you need some form of critter that can and will keep the corralline algae "in check".... my hermits does a splendid job of that! ;)

    Hi Kavir. The lower the K rating bulbs, the less coralline will grow.Even further it will tend to grow less under MH's as compared to T5's, at lower K rating.

    Depends. If I have to rearrange stuff in the tank, then gloves [bristles from the bristleworms] otherwise bare hands...

    Kavir, try and get a Tuxedo Urchin. they do not have long spines so the chances of getting stung is very small. This guy loves coraline and just about any other type of algea.
