Bio balls in sump.

landon531 · Jul 9, 2014

What are everyone's thoughts on bio balls. The sump I am getting has them but I was also thinking about replacing all or half of them and mixing with live rock rubble. Where could I find out the aggressiveness of certain fish compared to others?

On the fish subject just ask which fish you want to put together and well let you know. Tangs believe it or not can be very territorial and aggressive like yellow tangs. Try not to have more than one of the same family. I know you see tanks with like 4 yellow tangs but they are usually large tanks. Todd TJ's reef on R2R is really good with fish questions of that nature. I would ask him. Very knowledgable person.

Bio balls work if you clean them often they collect detrus but I would go with rock rubble or rocks in sump

Definitely would prefer the rock in sump.

I am currently running both I have a chamber for bio balls and a chamber for live rock, I've been happy up until now with the bio balls but after reading a lot of posts and peoples opinions I am deciding to change my bio balls over to live rock as we'll!
