Hi! I'm hoping to start my first axolotl tank cycling soon, but I haven't decided on a filter yet.
I keep seeing sponge filters recommended since they offer such minimal water disruption, but my one concern is that when it comes time to replace the actual sponge itself, the whole tank would need to be cycled again.
Is there a way to avoid that? Can you simply add the new sponge in a week or so before removing the old sponge, giving time for the beneficial bacteria to grow in it?
Thank you! :happy:
