Can't boil this piece of wood but will soak it in hot water. Picked it up yesterday from the forest/creek area by my house.
Is the fizz reaction normal? I know that if you spray this on rick and fizzes you shouldn't use it

Who ever said to put hydrogen peroxide on rocks? Peroxide fizzes on contact with all kinds of things. Vinegar is meant to be used on rocks to test if they contain calcium that will raise your PH a little. (Which is pretty useless anyway, imo)
Cool thx...any tips on making this piece of wood safe to use in my 125?When Hydrogen peroxide is strayed on anything laden with organic matter, it fizzes because it is oxidizing anything easily soluable (hence part of the name oxide).
If you take a mouthful you can feel it fizzing away (oxidizing)organic stuff in your mouth, and on teeth.

Wish I had some rain barrels laying around. I do plan on buying some come spring. But excellent safe idea.The peroxide may have rid the wood of any parasites, or bacteria that came from the stream. Although if is was in the stream, there are some that could be inside the wood the peroxide couldn't get to.
One way to be sure is submerge it in a tank of scrificial fish for a few months to see what happens.
I often soak wood in rain barrels a few months before putting in a main tank, and drop a few of those "sacrificial" individuals with it.
for some large pieces I soak them through the winter, where the water freezes solid for a few months, before adding it to a tank with "important" species.
I'll try this for now but do you think vinegar will do the job? I hate bleach.For a piece that size, I put it into my tub like you did (we don't use the tub) filled with old tank water (no solid waste) and put in regular unscented bleach (do not use the splash-less kind). The wood was submerged in the bleach solution for 2 days. Drained the tub, and let it soak in old tank water with Seachem Safe 200g dosing for a couple of days. Drained the tub, soak in old tank water for a few days. Added Safe again, drained and soaked for close to 2 weeks.
I did this for 2 pieces of the same size wood. No ill effects on the fish that I've had in with the wood.
