Are you asking if the UV sterilizer inside the Sunsun is detrimental to the filter?
I think he wants to slow down the flow rate for the UV to be more effective and he's wondering if the slower flow rate will harm the filter
Whoa.... Sorry about that guys. That was one of my no thought at all posts.
I was wondering if 1. the UV actually works well 2. It does not reduce the flow rate of the filter and 3. if I should buy it.
Really sorry 'bout that. I wasn't really thinking.
