Bio ball pics whats your thoughts?

Here it is. I talked about my yellow gunk in a previous post. I am slowelly removing them and wondering what you guys have for imput on is this my nitrate issue?

 

Those are the cleanest BB that I have ever seen. I dont think thats your No3 problem. Luna

 

Really maybe the pics are bad because the balls are full of gunk! I wish the pics were better of the gunk and not the ball. Damn this camera haha

 

I think the pics are fine, you should have seen my BB on my former W/D. You almost couldnt see blue anymore. Luna

 

Luna's right they don't look bad at all. That looks to me like just normal build up but its not bad. I have seen a lot worse.

 

Wow Really they have all this slime like yellow stuff on them. mad me think nitrate factory. ?Hey im glad its been wors because I thought I was doomed

 

In my opinion, Bio-Balls should always be replaced with Live Rock

 

I have maybe 1 lb per gallon. I am adding more slowely but dont know how to do that? and Can is be done at once or should it take time?
