Hey there,
I got my first betta in a long time recently, (mort) and I have a regular filter but stalking Reddit I realized a sponge filter is better. (I think) I have him in a 10gallon right now. I want to switch over to the sponge filter but I’m scared to lose the bacteria in the original filter. Does anyone have any advice for the best way to do the transition without hurting my fish?

Do you have any sponges or bags of like bio-rings for beneficial bacteria to grow on in your current filter?
Keep the HOB filter running at the same time as the sponge filter. After a month, the sponge filter will have enough BB and you can safely remove the HOB filter.
