ヒノ 5 Overall :Works very well so far. Need some more time to see results.Few cons so far :The flexible tube being transparent might be a cause for algae and some leaking occurs at the tube-to-pvc join but nothing some good taping can't solve. (Tape is included which is a plus)Some nice points:Pump is included which is very nice, and works well so far with the appropriated timer and plug.Pump is really silent btw. At least i can't hear it.*The reservoir is not included so need one for this to work.
