Review on 🔍 Fluval Intake Strainer with Checkball for Fluval 305, 405, 306, 406: Optimal External Filter Accessory by Brittany Smith

The original Fluval inlet filter with test ball should be CLEAR so you can see algae build up and know more precisely when to disassemble and clean. The one I have is solid black so you can't see anything. In all my years of owning Fluval filters, I've never seen this part do anything other than transparent. The change is not acceptable to me. I have initiated a return with Revane.
