I got my 2227, installed it and now its running. I have the hoses the same length and its between 100cm and 120 cm from the top level of the water. Its cycling but the level in the filter on drops to the bottom of the top basket of media then the stopper closes off and then it starts to fill again. Should the water drop to the bottom of the lower basket before it closes off the flow. I don't know if this is a factor but instead of using the spray bar I used a fluval rim adapter with the goose neck outlet and I have some extra slack in the hoses. Any help would be great.
