Easy-to-use internal filters for keeping aquarium water clear and healthy.

Fish constantly excrete both dissolved waste (ammonia) and solid waste. Unless this is removed from the water, it will quickly accumulate and pollute the aquarium, resulting in sick fish and a dirty environment. TetraTec IN plus filters work both biologically and mechanically to remove dissolved ammonia and solid waste, thereby keeping the aquarium environment suitable for your fish. TetraTec IN filters also re-oxygenate water as it is recirculated, further improving conditions.

• Easy maintenance - no need to remove the entire filter, as all components can be quickly and easily removed in-situ
• CE certified, TUV/GS tested - safety and reliability assured
• Adjustable flow-rate
• Filter sponge split into two segments - one can be replaced whilst other maintains population of beneficial bacteria
• Outlet nozzle can be rotated 180° for flexible flow direction
• 2 year guarantee
• Activated carbon sponge also available, for cleaner, clearer water 2-year guarantee

Application:

Simply attach your IN plus filter to the side of the aquarium using the suckers provided, ensuring that it is submerged. The flow rates can be adjusted with the flow-control dial, and the flow can be redirected with the rotating outlet. To clean the sponge, simply wash it in a bowl of aquarium water, but NOT under the tap. Tap water will kill the friendly filter bacteria. Wash or replace one sponge at a time. Always read the instructions carefully before use.

The TetraTec InPlus 400 has a flow rate between 200 and 400 lph with a power consumption of 7w
