    I've been wanting to use some lava rock in my tank, but I am seeing conflicting reports but no empirical data. Not one person has said it crashed their tank out of 10 or so post that I've read. Has anybody soaked the rock in ro/di water and tested for TDS and Iron? If not I'll do it in the...

    After six months of research and web browsing in anticipation of reviving my sw tank from 1983, I discovered this site. Just what I have been looking for. I am thinking of reusing some of my old 75 gallon set up. Reverse flow underground filter with cannister, sump, sculpted lava rock on...

    I got couple cool looking pieces of very porous lava rock from Maui island. I saw corals live on them quite happily. Is there any reason I should not use the pieces in my tank ? Thanks.

    Hey guys. Ive been wondering if you could use lava rock as a filteration system. I seen people put rock in their sumps and was wondering if i could do the same with lava rock. Im not sure if the rock they used was live rock or just an ordinary porus rock. If anything, let me know. Thanks

    Ok so I was thinking of making a 30 gallon soft coarl tank with lava rocks. only thing is when I put a large piece in the bucket to establish it in, I found that it floating.

    I have about 4 pounds of live rock in my 14 gallon tank and 5 pounds of lava rock. I plan on getting alittle more live rock soon but not a whole lot because that lava rock I bought is like uber porus! And yes. I think I did spell porus wrong. Lava rock is just the base rock they had at pet co...

    I am looking for large decorative pieces of lava rock (normally found in freshwater tanks). I want it for base rock. PM me if you have some. I can order it or just pick it up from the local pet store, but thought I would check here first. Chris
