Frequently Asked Questions - EX 1200 Plus TETRA

How to install the Tetra EX 1200 Plus filter?

Install the filter outside the aquarium, at a distance from the water level between 80 and 150 cm. Mount the inlet and outlet pipes, connect the hoses, then prime the filter by pressing the priming button rapidly until water flows.

Why is the water flow reduced?

Check that the hoses are not kinked or twisted, that the intake strainer is not clogged, and that the filter media are not dirty. Clean or replace the media if necessary.

How often should I change the filter media?

Tetra FF synthetic wadding should be changed every month, Tetra CF activated carbon every 2 to 4 weeks. Tetra BF biological foam and Tetra BB bioballs are cleaned every 6 to 12 months depending on dirtiness.

How to clean the filter rotor?

Unplug the device, remove the filter head, unscrew the rotor cover, take out the rotor and clean it with hot tap water. Reassemble everything in the 'lock closed' position.

What to do if the motor does not start?

Check the power supply. If the rotor is blocked or missing, clean or replace it. Ensure the rotor shaft is not broken.

Water leaks from the filter head, what to do?

Check that the locking clips are properly closed, that the head gasket is correctly positioned and clean. Clean the contact surfaces and replace the gasket if damaged.

Can I use the filter in saltwater?

Yes, the Tetra EX 1200 Plus is designed for use in freshwater and saltwater.

How to prime the filter correctly?

Open the stop valves fully, press the priming button rapidly several times until water is visible in the outlet hose, then plug in the filter.

The filter makes an unusual noise, why?

This may be due to trapped air (gently shake the filter), a clogged prefilter (clean it), or poorly connected hoses (check the connections). Lubricate the O-rings with petroleum jelly if necessary.

What is the difference between the EX Plus models?

The EX 400, 600, 800, and 1200 Plus models differ in flow rate, filtration volume, and aquarium capacity. The EX 1200 Plus is suitable for aquariums from 200 to 500 liters with a flow rate of 810 l/h in operation.

Air trapped in the filter.	Insufficient distance between the filter and the water level in the aquarium.	Position the top edge of the filter head at least 10 cm below the level of the water.
	Filter media clogged. Clean the filter media.
	Air entering through the intake pipe.	·Route a hose between the intake pipe and fil-ter below the level of the water in the aquar-ium. ·Renew the O-ring on the intake pipe.
The filter does not start up correctly.	Filter media insufficiently cleaned. Clean the filter media.
	The filter media is contained in nets. Do not use filter media in nets or nylons as the filter will become clogged.
Unusual noises emitted when the filter starts up.	Air is entering through the hose connec-tion.	Connect the hoses properly.

	Air trapped in the filter. Carefully shake the filter to allow the air to es-CAPE.
	There is a sound of air being emitted from the outlet pipe about every 10 seconds.	Air released by aquatic plants during photosyn-thesis and by bacteria causes the formation of air bubbles, which cause this sound. No mea-sures necessary.
	The start button is pressed. Never press the start button when the filter is operating. Ensure that no objects accidentally press against the start button.
