Can anyone define what bug this is?[Pic]

I cant get these things out of my rez, Ive cleaned the tank and bleached it, they come back, I put a shit ton of 33% H202, they swim in it and laugh, I dumped enough pyrithium in the rez to kill a cow. kills a few maybe but not enough to notice. I bought mosquito dunks and used 300x the recommmend does, they loved it. Then I bought some real expensive liquid drops for mosquitos,flies and gnats, One drop is supposed to treat 50+gal, I put 6 drops in my 30 gal. It did nothing. I have a few of those gnats that fly around and get stuck on the yellow stickys, I think this is there larva. They jump like little fleas and slowy seem to grow to almost a tiny thin worm. I cant seem to get any focus on this point and shoot to get closer. The plants are losing yeild from it for sure so i am pretty sure they are root eaters. From my research I assume thrips or fungas gnat, but I have tried all their known chemicals with no results

They're in your root system is why they keep coming back.

can tell by the picture but by the sounds of it you have springtails. some say they are beneficial but i say kill them. i cut a potato in half and put it on top of the soil. a day or two later you will see thousands of them. bait them in with a potato and sprinkle de on them. diatomaceous earth.

rez my bad didn't thinkyour in hydro. i think you have to use de dry. still sounds like springtails. they eat organic matter and like really wet places. jump around and are fast.

Thanks, i have de in the barn i can put on my mothers. This crop too infested to get rid of but for nextt ime i wantt o have my preventative ducks in a row so i will research speingtails thanks
