I don’t want to turn this blog into one about aquariums, but now that there’s an aquarium connected to the plant tank it’s part of the whole aquaponics system. Now that we have decided to use a normal hobby aquarium as fish tank we might as well spend some time making it look nice as a normal aquarium. If you’re not romantic at all you could just drop your aquaponics fish into a big black plastic basin – I don’t think the fish would mind.
We wanted to add some roots to the aquarium to try to recreate a real and natural looking environment, so we threw in a few pieces of wood that we found in the forest:
The problem is that the wood keeps floating since it’s not saturated with water:
The root to the right seems to be able to stay submerged. The other two are probably branches or stems.
The wood was left in the water in the aquarium for two weeks to allow it to absorb water to make it heavier so that it would sink to the bottom. What happened instead was this:
Nasty mold and what is probably tannin leaking into the water, changing the color of the water to light yellow:
Pretty nasty setup and delay before we’ll be able to add fish to the system.
The floating pieces of wood have been thrown out and the water has been changed. New roots from the pet store will be added together with stones to create the right look.
And now I’ll go open the door for the postman – he’s here with the water test equipment and nitrobacter 😀
