I'm originally a salt water guy and became pretty obsessed with it but i took a couple years off and now i'm jumping back in. I've always wanted to do a cichlid tank. I have a bunch of old dead liverock from my salt water tanks i was wanting to use in the display tank. Has anyone done this before with cichlids? If anything i would think the help to raise and maintain the PH level. If someone has done this can you post a picture? Do you see any negative effects in using it? The old liverock will provide awesome territories for the cichlids over using river rock.
