Bio balls

[cgr]

I have a well established tank with a 5+DSB. The tank has been operational for about 2 years. Originally, I had CC but switched to DSB about 5 months ago. Should I keep the bio balls in my wet/dry or take them out?

How much LR do you have in the tank?

I only have about 40-45 # but plan to buy another 50# soon.

11 fish is a fairly high bioload. If your nitrates are undectable I would leave it be. It seems to be working so why change. Especially in a FOWLR tank.

I would keep the bioballs in. Occasional water changes or a nitrate spike is better than having an ammonia spike, which would be possible with your bio-load.
