For those who've sunk driftwood, how long did your take to sink?

I got 2 smallish pieces to tie my anubius and java fern to and I got picky about what pieces I wanted and now I suddenly don't want to bury them. Lol I was gonna have them soak until Monday(water change day) and if they haven't sunk, I'll cave and bury them a bit.

I've usually been able to get driftwood that sinks. I did get three pieces free with a tank that I never could get to sink! Most of my driftwood is mopani, which is very dense and the one (huge) non-mopani piece I have in my 125 only had to soak about a day to become just slightly negatively buoyant.

My main pieces are mopani
I had gotten these smaller pieces because they were $3 a piece and to tie my java fern/anubius to

Mopani in my experience almost always sinks immediately. It does have a habit of having lots of tannins though.

I have had one piece of unidentified driftwood that's taken about 3 months to sink, and it still has to be partially buried to avoid it floating a bit.

You can always get stainless steel screws and secure the wood to a base piece of rock (drill a hole in the rock using a masonry bit, depending on the rock's hardness), or you can simply secure the wood to a piece of acrylic and just bury the acrylic base under the substrate to hold the wood down - if it's not too buoyant. Make certain any screws are stainless steel, preferable rated for a marine environment.

I should clarify, the pieces in my tank are mopani
the pieces that I am trying to sink are most likely not

They haven't sunk yet. They were in a bucket nearly an entire day and weighted underwater overnight. I'm giving them a boil this morning as I read it sometimes helps "uncorking" dry pieces.

one small piece of my wood took around 4 days to sink,it just floated
around the tank happily minding it's own business ,then begrudgingly sank.
this bit of wood does this every time without fail,when i have dried it out,
and stored it away for another time.

well boiling doesn't seem to have helped. I just decided to let it float around the tank until tomorrow. if it's still floating, I'll partially bury it and check back up on it next week during water changes.

In my experience every piece of Mopani wood I have ever had wouldn't sink till they got water logged really good. No matter how big or small. Some would take a couple o!f days to a couple of weeks. The few pieces of Malaysian driftwood I have sank from day one..

I ended up burying the pieces. And I think I like them better buried. Seems much more natural


I tried to get a shot of the Willow Java Fern, but it came out rather reflective :p

I bought a branchy/root type of driftwood (not sure of the type at the moment) that tends to float. It was a larger piece though. Most of the time they are sold attached to slate rock, but this one was just loose at a reduced cost. I let it float in the tank to give an amazon look, but it sank slowly all the way to the bottom in about a month. It still moves easily, but does not float at all now. It was too big to boil or pre-soak, really, but it was about a month.
