Travertine rock

[ZoWhat]

Can someone weigh in on the reef safety of using travertine rock as 3x3 tiles to grow out zoas?

Travertine - Wikipedia

en.m.wikipedia.org

Under Geochemisty it states:

Both of the major calcium carbonate minerals, calcite and aragonite, are found in hot spring travertines; aragonite is preferentially precipitated when temperatures are hot, while calcite dominates when temperatures are cooler.[37][38] When pure and fine, travertine is white, but often it is brown to yellow due to impurities.

Impurities? What impurities?

Im still a little unsure Travertines use in a DT to grow zoas on

If you're not 100%, why not just stick with standard fragging plugs?

From a safety perspective, if it was 100% travertine, it likely wouldn't cause any harm, however, it would be expensive and pointless. Travertine is derived from limestone, the difference being the porous veins that run through the stone, which *can* contain heavy metals and contaminants.

If one wanted to specifically grow out zoas into a square, there is plenty of other media out there that would accomplish the same task with no risk of leaching and a MUCH smaller sticker price.

Limestones (of which travertine is one kind) should be safe if uncolored and uncoated. Coral skeletons are biogenic limestone, after all. Marbles are probably best avoided as those are metamorphosed (think deeply buried, exposed to warm hydrothermal water and dissolved metals).

I've been using these lil jerk-A tiles for awhile. Cone to think of it, zoas have been acting weirdly for 6mos... I THINK about the same time I reintroduced these 3x3 tiles again

AAAAAAAAAAAHHHHHHHHHHHHH dam it

Here's what they look like:

Yeeeaaaah. If it was me, I'd get 'em onto something that you're certain is reef-safe.
