    hi

    iv been keeping these rocks in a bucket, the coral skeleton had 3 mushrooms which died and i never did a water change, which i think is the problem. anyway the rocks have gone green, a very dark green. can i put these rocks in my dt and will the green sread to all the other rocks in the dt? how do i get rid of the green? only one side of each rock has gone green the bottom still looks ok.

    Green hairy Algae= GHA
    But, this does not look like GHA, I know what it is but do not know the name, wait for @Tony or the other gurus to answer

    I somehow doubt it GHA. Was the rock exposed to light at all?

    It's probably an alga of sorts but rinse the rock off in fresh salt water and give it a scrub with a nylon brush to remove the alga. Smell the rock to see if it smells like the sea or if it has a rotten egg smell or any off smell. If it doesnt smell lekker put it in some fresh salt water (not the water used to clean it) and add an airstone or small pump to move and aerate the water. Leave it till the putrid smell is gone which may be anything from a few days to two weeks. If it smells ok then add it to your DT.

    Malooda, it will only spread if there are nutrients to feed the alga. If your tank is low in nitrates and phosphates and you have a few herbivores it will be gone in no time but give it a good scrub with a brush first.
