OP's issue is over now. But in response to your comment...
Can see your thinking here, but I have excellent results keeping additional media in the tanks for bb to attach to, to adjust to levels as they should rise and fall. When I didn't do this, fluctuations in my water parameters allowed a less stable tank, and more problems in my tanks. Just relating my experiences here. I am not a scientist and have never purported to be, but I keep some nice tanks and aquatic creatures, and the extra media has been useful for me. I have seen more stable tank parameters and had much less loss of fish life, etc.
OP and you can keep your tanks however you wish you have the ability to decide for yourself, since the OP's issue is over, this is my last post on this thread, feel free to PM me if you need to continue the side topic.
