Swell Flocor is a perfect biological filter media and it is widely used in pond filters. It has a large surface area on which bacterial colonies can thrive, breaking down nitrite and ammonia in the water and lowering the risk of water quality problems.
It is very easy to use, simply add to the relevant chamber or section of your filter, no mess or fuss.
The durable material provides long term performance and needs next to no maintenance. If rinsing is necessary only do so in pond water, to retain the bacterial cultures. As you'd expect from us here at Swell, it's always at a great price and with speedy delivery options.
Flocor is commonly used in multi chamber filters such as those used with Koi, to provide the very best results where they are needed, and deal with large quantities of water.
