    Thats diatoms then. It often appears when you change things to your tank.
    Did you cycle with the lights off?

    Diatoms look ugly but it will clear up quickly..just make sure you keep parameters in check.

    Calcium wont accelerate diatom growth. Diatoms make their skeletons out of silicates. They also require light so hence didnt pop up while you were cycling. Having diatoms is not a big deal at all, they a normal part of cycling a tank.

    You dont have to feed the shrimp plankton. You can target feed it small bits of fish/shrimp etc. Most of the plankton you add will never make it to the shrimp anyway.
    Leathers do not require the addition of calcium as they have no calcium skeleton like hard corals. Always check the parameter before dosing.

    Leathers are photosynthetic so you dont have to feed it anything. The addition of coral food will make it grow faster, but if it looks healthy id leave it.

    I see in our other thread that you have had diatoms before.

    Can you perhaps post a pic of your tank.

    so am i correct to say calcium will only be necesarry for hard corals?

    my soft coral - looks very healthy, but sometimes during the day it goes limp and small... is that common?

    I just add marine snow to my system for my softies.
    Like was said softies like leathers and mushrooms don't need Calcium.
    The "stony corrals" the ones with a skelaton will benefit from Calsium.
    Just don't look at the spelling, not my day today:tt2:

    Youll need to keep your calcium constant no matter what corals you keep. Hard corals will require more but other things in the tank like coralline algae also needs calcium.

    Leathers do sulk every now and then.

    Reading through the other thread it sounded like it was diatoms. What are your tanks parameters? When last did you do a water change?
