If you are just setting up a new tank I'd simply toss it in and let it cycle. It will probably be a long cycle but the whole point of live rock is the bugs and bacteria that live in it. Let the rock cycle and the corraline will grow in eventually.
If you tank is already running and stocked I'd let it cure in a tub with a powerhead.
Yeah my tank is fine, its under liverocked, but its also tremendously understocked so it works out.
Well heres the thing, this stuff is in really bad shaped. i cleaned the dirt off but its still really dark and wouldnt look nice and thats part of the point for me.
will curing it help it get that light brown color again?
Im just trying to figure out what to do before filling this huge tub with salt water if im just gonna have to bleach it to get what i want and waste the salt.
