I just put my first order of 45# of LR
in my new 75g tank. Small amount, but building it up.
There appears to be some sort of white stuff growing on a couple of the rocks. It kinda looks like spider webs you see a spider make in a plant or something. Any ideas what it is? Also have some greenish/brownish algae? growing. Is that normal with new LR
Thanks in advance from anyone that might offer help.
