Easy Water Filler manual level controller (Refill with aquarium bottle)

To set the water level you want to keep it is necessary, then, cut the supplied tube to the right height to maintain the aforementioned level (as per the attached photo).

It is advisable to cut the tube with an inclination of 45 ° instead of transversely in order to minimize the noise of the bubbles during the top-up phase.

The 2 pieces of tube thus obtained must be mounted on the adapter; The shorter piece will be the one from which, once the water level has fallen, air will enter the bottle by dropping the water into the aquarium through the other piece of tube (longer) thus keeping water to the desired level.

NB: avoid cutting the tube into 2 equal parts otherwise the functioning of the product is less the operation that is based on the principle of communicating vessels; One of the two tubes must be longer to be able to remain below the water level while the other tube passes air
