Bio-balls in a wet dry support the biofiltration of the tank. Ammonia to nitrite then nitrite to nitrate. In a non planted tank, nitrate accumulates and is removed by water changes. In a planted tank, the nitrogenous compounds are/can be used by the plants. What do you measure for a nitrate level? I think it may be good to take a step back in all of this. Rather than ask these questions as you go along - why don't you tell what it is that you are trying to accomplish with you tank. Then folks here can help you reach your goal.
