Tetratec Internal Filters are designed to be simple to use, whilst at the same time delivering excellent performance. The TetraTec filters benefit aquariums and fishkeepers in a number of ways. They contain an improved venturi design that blows air bubbles into the aquarium without any loss of flow rate; this improves aeration of the aquarium, without any loss in filter performance.

They are also built with a split filter chamber that ensures each filter contains a minimum of two sponges; which allows one sponge to be cleaned or replaced, whilst leaving the other one in-tact. This helps to limit the loss of beneficial filter bacteria during maintenance, thereby maintaining water quality for your fish. They have a flow adjuster that allows the flow of water to be reduced. This is beneficial for smaller aquariums, or those with fish that prefer a calm environment.
