U may consider water pass through the negative presssure approach (the same method used by 濾桶). U can connect the 濾桶 and then 潛水泵....PS it's better to use the wet/ dry 潛水泵 to do this
yes, that's the method I used before, it works, but the connection is not simply, and it is difficult to "start" the filter to work after you clean your "filter", besides, I don't see this as a cheaper alternative if we are talking about 1000L/hr to 1200 L/hr only, buying a bigger filter is always cheaper and convenient. A good wet/dry pump that works as silent as an external filter will cause more then the filter already
