Thank you for your feedback! This is what we thrive on! We will make some adjustments to resolve this and make it better thanks to your review! We do try to keep the gaps as minumal as possible to keep the water flowing throught the adapter, but our goal is to make it fit without modification. The cycling can take a while on a fresh roll, I would give it at least a week, maybe two, depending on how dirty the water column is. Once the fresh roll get dirty enough it should start cycling normally. We are always here if you need any help, just email us at sales@kreativereefer.com. Thank you!
