i recently had a huge problem with a small cheap tank that i was given. long story short i had to replace it so i upsized to a marineland 10 kit. the only fish in the tank is a half moon betta. he loves the space but cant use it all. the penguin 100 power filter bio wheel that came with it is too strong for him and pushes him around. usually people want to know how to make their bio wheel spin faster i want to know how to make the filter a little weaker. is this possible, or do i need to replace the filter?
