RO Membranes For Aquariums & Ponds 

If you’re installing a pond in your back garden or if you own a large aquarium, then reverse osmosis membranes are a fantastic filtering option for your fish. 

Reverse osmosis works by pushing water through a semipermeable membrane but blocking any contaminants that can be found within a water supply.  They are incredibly effective, removing 90-99% of contaminants in water.

RO membranes are a great option for fish aquariums and ponds because of their ability to control algae growth, reduce harmful chemical contaminants, and filter solids and sediments.
