-
Wood Buoyancy: Many types of wood used in aquariums are naturally buoyant and may require soaking to become waterlogged and sink properly.
-
Temporary Weighting: Initially, to prevent buoyancy, you may need to use additional weights such as rocks or anchors to keep the wood submerged until it becomes fully waterlogged.
-
Tannin Release: When introducing wood into your aquarium, it can release tannins into the water, creating a visually pleasing cognac-like tint reminiscent of natural river systems. Tannin levels can be managed through regular water changes or by utilizing products like Seachem Purigen in your filter. It's essential to note that tannins are not harmful to aquatic organisms.
-
Tannin Control: If you wish to minimize tannin release during the initial phase, you can boil the wood in water for a few hours to remove as many tannins as possible. Alternatively, you can opt for soaking and performing water changes until you achieve the desired water clarity.
-
Mould and Biofilm: During the initial setup, you may notice the development of white fungus-like growth or biofilms on the wood's surface. If this occurs, gently scrape and use a small tube for suction to remove it regularly. Typically, these growths will naturally disappear within a month after the initial setup.
-
pH Impact: Be aware that the presence of wood in your aquarium can lead to a decrease in pH levels in the water. It's advisable to monitor and adjust pH levels as needed to maintain a stable and suitable environment for your aquatic inhabitants.
