Before it goes in
- Petrified Wood is inert: it will not move KH, GH or pH, so it is safe in a shrimp tank and in soft water.
- Before it goes in, rinse it.
- 5 different pieces of Petrified Wood are modelled, so the one you place looks like one you could actually pick out of the bin.
- A default piece is 18 × 8 × 8 cm (7.1 × 3.1 × 3.1 in); you can stretch it to whatever you bought.
Petrified Wood: care and setup
Does it raise pH and hardness?
No. It is inert, so KH, GH and pH stay where your tap water puts them.
Do I need to prepare it?
Yes: rinse it before it goes in.
Will it tint the water?
No.
What it goes with
- Plants you can tie or glue straight onto it: Anubias nana 'Petite', Subwassertang, Anubias barteri and Bucephalandra 'Green Wavy'.
- Substrates that leave the water where it is, the same as this one does: Walstad, ADA Amazonia and Colored Gravel.
