BlueLineAquaticsSC Posted February 16 Share Posted February 16 My dad is in town and wanted to go somewhere I’ve never ventured, a saltwater store. He was asking questions about live rock and wanted to know if he could use lava rock. The owner said it’s fine for fish only set ups but will kill coral and inverts, due to it having a lot of metals. I’ve used and seen lava rock with neocardinia before, I’d there any truth to what he said or is it maybe specific to saltwater? Link to comment Share on other sites More sharing options...
