Lava Rock???

[Super Elephant]

Need some advice....

Is lava rock suitable for marine fish tank?

Recently, I bought a sera "enjoy your saltwater aquarium"...... It says lava, tufa, dolomite rock are also suitable materials for the marines....

How true is this? Anyone got any expereience?

They might be suitable but just go for LR for Lava rock and other kind of rock will look weird together with LR cos the colour will not blend well...

It makes the other rocks look odd 1 out...

u dunnoe wad types of minerals are inside the lava rocks.. so u can't be sure that the minerals wil harm the fishes and corals or not.. that's y ppl go for live rocks.. not lava rocks..

lava rocks are famous for containing many types of minerals..

What kind of minerals? And what are those that are harmful to the fishes?

No... lava rocks... the brown ones sold in LFS (and not the real volcanic lava rocks) are totally inert and if you wash it properly it's totally safe to add them into Marine Tanks. Their porous nature might even help in housing beneficial bacteria.

But... They look weird lah...
