of course. but advances are made sometimes by taking old technologies and applying them in a new way. im not claiming to have invented that but this is valuable because of the following:

just makes for expandability and reconfiguration while the system is still full of water. just lift the tubes out of the water to seperate that bucket/unit/bed/res from the rest of the system. you can have multiple length hoses, I have tested 2 units 20 feet apart and the flow is still the same. i can connect 8 units with 1 siphon sump. and you can make redundancies so there are like 4 tubes per bucket, that way if 1 tube clogs you got 3 more that will hold. also there is no need for a big res, the res connects to other units so they all feed back into res simultaneously. the pumps can be moved from res to other containers in the system if needed. if the res is pumped out and its waterline recedes 1 inch, all the other units will transfer their water into it until its waterline is the same as theirs. all the waterlines balance out simultaneously. the only hard part is forming siphons in these sumps so they are permanent but I have a fullproof way of doing that now...
