[Zappy Kiwi]

Hi. THere are several white patches growing on my life rock which i just inserted into my tank for a day. Wat are they? HArmful? neutal? good? Should I just leave it alone or do some cleaning to it? pls advise.

Also, I have seen some small white worms (larve worms??) floating around in the tank after i introduce the rocks. Is it suppose to be like that?

well, they may come from the LR as hitchikers

Sorry, I dun have a digital camera at home.. took it with a hp camera... that's why a bit blur blur. Anyway, the white stuff looks like a web of cotton wool on the rock...

The strange thing was, it wasn't on the rock when i inserted the rock the night before..... wat is this white cotton looking thingy???

I realise that I the reddish tinge and purplish tinge of colour on the live rocks have faded and become pale... why is that so?? Is it because my tank is still in the cycling period? Must I add any chemicals to the water to enhance the colour of rocks??

Sorry for asking so many questions in one short!! new to this marine hobby and getting more and more excited...

BTW, I have oso find a fan worm growing in one of the live rocks. Will it die of during the cycling period?.. (i hope not... i kinda like this creature... shrinks to its hole when i look at it... ) pls advise. thks
