Lava rocks in brackish tank???

[datnoids81806]

Is it safe to use lava rocks in a brackish tank setup? Thinking of setup a tank with lava rocks and sand substrates for some GSP.

Should be fine.

Great to know about the answer!

Allot of people use it in a sump for bio so it would work. It would look crazy though. Id say look at Texas holey rock or Florida limestone reef rock it you want a cheaper alternative to say pukani etc

I have it in my brackish sump, and some odd pieces in the tank. No problems, and when I changed from fresh to brackish it cycled in fast. It's my live rock, but I have other bio-media.

I also have Seachem Matrix in my filter

Lava rock is inert and perfectly safe. Looks pretty nice too

Years ago on one of the national salt forums maybe reef to reef or reef central there was a guy who made a Hawaiian island tank he used lava rock and black sand and mangroves to build the island. It was really pretty cool. I just did a search and couldnt find it some like it probably copies but looked like they were using reef rock.

Do I need to RO water for the brackish tank?
