they make the tank look ugly and i dont want an ugly tank. Brown water isnt appealing at all. right now i am soaking them in a cooler that keeps the water really hot. change it 3x a day
Just come in on this post,i am curious,why people don,t like tannins in their tank,its natural for a lot of fish,& it really brings out the colours,particularly if you keep Tetra,s,Barb,s,rasbora,s etc.
If you want to get rid of it a bit quicker,you can bleach the wood,but you still have to soak it for a few days.
