Hi I recently bought a sunsun hw-304b filter for my turtle and I have a lot of trouble getting the tubing to be secure.
It might be incompetence on my part, but even if I push the tubing in the valve ends as hard as I can and turn the knobs to secure it, it seems to pop right off even with the knobs tightened. Is this a common problem with sunsun canisters or am I just not securing it properly? If it's a common problem, is there any alternative way of securing it?
