Amazing.. I put 2 large pieces of bog wood in after soaking for days.the water turned a horrible yellow colour..I have done several water changes but after a day its back.
Add a juwel carbax.. after 3 hours the water is crystal clear. .in fact its the clearest I have ever had.
One word. If you are useing it in a compact bio 3 or above remove the old carbon sponge as there isn't enough room for them all.
