Aquarium Foam Filters - Pond Filtration Experts UK

Reticulated Polyether Foam (aka PPI Foam) is ideal for filtration in ponds and aquariums as it is chemically stable under water. This type of foam filtration is the life support of the pond or tank leading to healthy fish. It is commonly known as aquatic foam filters or pond foam filters or filtration foam.

Features include:
• Protecting the pump from debris
• Breaking down dissolved fish bio-waste
• Reducing nutrients that promote algae growth
• Aiding entrapment of smaller suspended particulates

Reticulated Polyether foam is very resilient to water (including salt water), humidity, soap, oils and lubricants. It can swell in the presence of organic solvents (depending on type and concentration). It can also be used as a bacteria carrier in biotechnological water purification applications improving the active surface & efficiency of the bioreactor.

Aquarium foam filter FAQs

How often should I clean the filter foam?

Rinse the foam whenever water flow through the filter noticeably drops, typically every few weeks. Always rinse in a bucket of water taken from the pond or tank rather than tap water, which protects the beneficial bacteria colony living in the foam.

How often should I replace my filter foam?

With regular gentle rinsing, quality reticulated foam lasts a long time; replace it when it starts to lose shape, tear or compress, as that reduces both mechanical and biological filtration. When you do replace it, run the new foam alongside the old for a couple of weeks if possible, so the bacteria can establish on the new sheet.
