Review on 💪 Enhanced Fluval 404-405 Tune Up Kit for Optimal Performance by Tricia Pence

Summary: This upgrade kit fixed a rattle/pop that was getting slower and louder over the last year! Details: I had a Fluval 405 canister filter for 7 or 8 years. It was plugged in and working almost all the time. Thus, the ceramic shaft and impeller show normal wear. As the impeller wears relative to the shaft, the diameter of the shaft is now smaller (thinner), which allows the impeller to "bounce" a little more when spinning than it should. The extra movement turns into an annoying hum/clatter. New parts have breathed new life into this reliable filter. I'm glad a replacement gasket was included as the old one had a flat spot all the way around; Luckily it hasn't started leaking yet. I used '3M Clear Silicone Paste 08946' purchased here from Revain to 'lubricate' the seal prior to installation to ensure longer seal life as the unit is regularly disassembled and cleaned.
