What precautions do I need to take?
Before installation or maintenance, or before putting your hands into the aquarium, remove the power supply from all the electrical devices under water. Read the instructions.
Check that all the components of the product are undamaged, disconnect all the electrical devices and make sure the voltage of the product corresponds to the mains voltage.
My Bubble Maker is producing fewer bubbles.
Check that the pump is not squashed/pinched, that the red valve is open and the silencer sponge is not clogged with dust. If the problem persists, thoroughly clean the pump and the rotor of the BUBBLE MAKER.
