Review on 🐟 Top Fin Silentstream PF-S Refill for PF10 Power Filters - 12 Count, 1 Year Supply (5.5in x 3.1) - Enhanced SEO by Sal Mattocks

We've been using our filters like crazy since we started raising guppies for a year-long school project. The filter is unique because it shows us when it needs to be replaced with a little red indicator when it gets dirty. this takes a while if we don't overload the aquarium with too much food at once. Going to the store for them every month was exhausting when we could just buy those 12 packs and cut our trips down significantly.
