View Full Version : Petrified wood?

Has anyone used petrified wood for your tanks? I was looking at some on ebay and man, that will look nice in my SA cichlids tank! Just not sure if it is safe, any comments?

My lfs frequently sells it specifically for use in aquaria. What I've used has at least seemed to be inert, so fine for use with fish...meaning that it hasn't had any impact on pH and hardness. It would be nice to know exactly what the metal content is, though...

I have some petrified wood in my tanks. No problems. :ok:

Me too, I have a fairly large amount of it. Looks great. (And yes it is inert and won't afect your PH.)

Yep, great looking stuff and safe in the aquarium :ok:

my wife has about 10 pieces of the stuff but i opted to use the slate instea...im sure at some point ill use it also just to make a more likable tank for viewing but im happy with mine as it is right now

with the exception of a few trace elements which could and would vary from sample to sample petrified wood i the exact same thing as silica/quartz/play sand that is in so many of our tanks (SiO2)....so have at it with no worries.

Hmmm, well I guess I got the ones with the few trace elements! I got mine today and I rinse them with boiling water twice and there is like an oily substance (and surely smells like oil). I scrub them with a brush and very hot water, but not sure if it is gone. I will submerge them again in boiling water. Any one has any idea what could be?

i wouldnt even chance using it.... is your mony spent on fish worth the risk?

I would err on the side of caution. Oily residue could easily coat the gills.
If you were lucky a scrubbing with a brush and a lot of dawn may be able to rid it.
However in that instance I would soak it in a bucket of plain water for a couple weeks
to see if any oils remain.

I just find out that the oil residue is due to the cutting process of the rock. the petrified wood that I got are the tops of larger ones, so they use a cutting process to get a flat bottom and so they use oil for the equipment to avoid overheating and stuff, so I guess some more boiling water rinses or a good scrub with Dawn should do right?

Warm water and dawn, skip the boiling part. A few good scrubs and an over night soak to test. Rinse lather and repeat until you have no oil.
