What the Blue Foam Sponge does for Aquis CF500 / CF700...
Aqua One's Blue foam is pretty clever stuff. Not only will it trap solid waste and hold on to it until you clean the filter out but it will also act as an efficient home for essential beneficial, aerobic filter bacteria which remove toxic ammonia and nitrite from aquarium water, contributing strongly to your fish's health. Add in great durability which means it can be rinsed and reused dozens of times and you can see that its worth seeking out original Aqua One filter foam for your filter.
The polymers the foam is made from are very durable in water so why change the pads at all? Sadly, over time, the open cell structure of the foam begins to break down and compress, water flow is reduced, less bacteria are cultured and the pads need cleaning more often. So, we suggest that you play it safe and change the foam pads in your Aqua One Canister filters, one at a time every six months or so to maintain performance.See all Aquis CF500 Spares & Accessories...See all Aquis CF700 Spares & Accessories...
