Thanks, I have been using the bark and sticks for as long as what I have been in the hobby for.
The sticks just start routing at the bottom, the part that is under the substrate, that goes for the bark as well.
I replace the sticks and bark maybe once a year or every six months.
But I have not had issue with the bark or sticks.
I just wash under hot water and scrub with a scrubbing brush and that is it!
If the bark and sticks start getting mold or something that I don't like I remove it.
On a stage I had a tank that had leaves mixed twigs.
Might sound funny but I washed the leaves in hot water let them dry and then into the tank.
Also had a tank that had wood chips.
My first every setups all those years ago, the only issue was the substrate was far to moist.
