structure question-newbie

I have an idea for some pvc structure and where to place it that I would like to run by y'all. The structure is simple and I doubt it's original. Nursery pots, big black ones, with about 15 or so pcs of pvc out the top and a few drilled into the side and placed on an upward angle. Then pour a third or half a bag of quik-crete to hold it all together and add weight. A plastic stump if you will. Placement would be on a decending point starting in about 6 ft of water and down to 20 ft or so. The pvc can be used if need be and the crete is sand mix so it tied it all up real good. Any input will be appreciated. I'm the new kid on the block and look forward to all the knowledge y'all have to share. I live in middle Tennessee and fish Tims ford and Normandy and woods res mostly. I've been here about 2 1/2 yrs from Florida. The structure and techniques are greatly different here and I'm currently learning alot every time I go. Great forum.

put bags in buckets before you pour crete in them and when they dry pull out of bucket. Or motor oil bucket sides before crete pour and thye will come out and can reuse bucket.
