Hi,
There is no efficiency drop in the new model of Hydra 30 filter although there is a change in the volume of water that it can support. The reason is because after receiving numerous feedback after the launch of the first version Hydra 30, we noticed that some of the hobbyist tank is keeping quite a high number of fish and the bio load are real high.
Therefore with this new version, we reduce the volume of water that it can support so that the efficiency of the filter can be maximise as we understand that lower volume will means smaller fish tank and lesser fish being kept in the tank.
Sorry that this has caused a confusion here.
