Small white moving bug in water???

I went to change out my water today and found there are a ton of little white organisms moving around in the water. They are very small like the size of a grain of salt and there are quite a few. The weird thing is my roots still look the same and my plants are still growing strong as far as it looks from the outside.

My grow is 55days now and im 2 weeks into flowering.
I change the water every week to week and a half and have never seen these before.

Anyone know what they are and if they are good or bad?

Any help is appreciated. TY

Spring tails?

"Springtails are another bug we see a lot of in summer wherever there is a lot of water. They are small and white-ish with a small hooked tail they use to spring and jump with. You often see them in the top of a pot or on the water surface in Aquafarms and other hydro systems. You know that these small white wriggly things aren’t a form of scarid fly lava because there are no flies around and they spring and jump. You can get natural predators to get rid of them but as they tend to come and go and do no real harm to the plant over a three month cycle, I won’t worry about them, they’ll probably just be gone one day. You can flush them away to a certain extent, and they don’t like Oxyplus"-GC

"I've seen a few springtails in the flowering area since the soap drench but very few. I found that my vegging area had them too, lots of them. I used one capful of Murphy's oil soap per five gallons of water instead of per gallon like I poured through the flowering plant pots, and let it circulate in the reservoir for about 12 hours, 2-3 tray floods, before changing it. No soap ever went into the reservoir in the flowering room, just poured through the pots and drained to waste. I haven't seen a single springtail in the veg room since treatment and the plants look great including young clones without a lot of roots so this seems to be a pretty safe and effective treatment. I'm planning to do the same to the flowering room just before the next scheduled reservoir change. Thanks for the soap tip, Buzz."-GC
