Hi!
I am arranging a DIY aquarium (800l) for discus. The tank is still empty (filled with tap water, actually).
I got a big trunk (the root of a tree, perhaps an alder) from the sea side. The trunk has been for a long time submerged in the sea water.
I cleaned and prepared the trunk as follows:
-I cleaned de trunk with an hard brush to remove the rotten wood and dirt.
-I let the trunk in flowing fresh water for two months, brushing it once a week.
-I boiled the entire trunk in a big metallic keg three times, each time about six hours. I let the trunk a week in fresh water after each boiling.
Now, I have the trunk into the tank filled with tap water. At this moment, there is no filtration or water changing active in the tank.
After three or four days, the trunk gets covered with a very delicate layer of something like mould. This “mould” becomes evident after a week, when I empty the tank and refill it again with new tap water.
This mould is white/grey colour. The thickness of the layer is about 1 cm (aprox. half inch) and the fibres are so thin that they almost can’t be seen.
I don’t know if this mould is really mould or not. I don’t know if it is some substance coming from the wood. I neither know if this could affect the health of the fishes and plants.
The pH of the water seems not to be affected by the mould and it is about 7,5 (to be corrected before putting in the fishes, of course).
Can anyone help me with this problem? Thanks in advance.
