American Fire Glass

XXL Black Lava Rock (4 in. - 6 in.) 10 lbs. Bag

$ 14 40

Overview

Lava Rocks will instantly give any old fireplace an exotic, yet classy look. Naturally occurring, these Lava Rocks are formed as volcanic magma rises to the surface, cools and releases gases which gives these rocks their coarse surface. Because they are volcanic, they can withstand extreme temperatures without sustaining any damage or crumbling. Lava Rocks may be used exclusively in a fireplace or fire pit, or may be used as a base or filler for other ornaments such as fire glass or Lite Stones. Whichever way they are used, the resulting effect is truly fascinating. The best part is that they require very little maintenance. Available in various sizes.

Questions & Answers

Can you use it in an aquarium with live fish? (Or is it poisonous?)

Can you use it in an aquarium with live fish? (Or is it poisonous?)
Asked by: paulbrittgarcia
I used it in my 75 gallon freshwater aquarium. No fish were harmed. I just made sure I prepared it by rinsing several times with hot water outside. Research is conflicting with boiling it, but some people say it can/will explode. So just be warned.

Lava Rock is a natural source from the earth, however, we cannot guarantee that it has had chemical free processing.

Is the lava rock natural? We're chemicals used to clean or treat the rocks? I am planning to use these in a fish tank.

Asked by: DF
We do not test this product for use in aquariums or fish tanks. These were not processed for this purpose. Lava Rock is a natural source from the earth, however, we cannot guarantee that it has had chemical free processing.

Wish there were more larger pieces. A 10lb bag was not enough for my 20 gallon long. In hindsight, I would recommend a 20lb instead. Even more if you have a larger aquarium. Overall, great for aquariums.

The rocks we're bigger than I anticipated but that was my fault I didn't catch the description the first time around. However, what is not my fault is the fact that I was given a 30minute window to cancel or change the order, that is absurd! I got 12 bags of rocks and I used 11 to cover a 2.5'x3'.
