Weird haze in water

[UnknownUser]

I live in USA new england parts and my water is decent, 7.2 ph 0kh 30gh with no ammonia or nitrates in it. But sometimes it just doesn’t look right. I’ll fill up my bucket (which has had nothing but water dedicated to water changes in it) and at the top is a layer of what almost looks like oils. I dump the water out and refill the bucket til I don’t notice it as much anymore, but sometimes after the water change my tanks are hazy like the water isn’t clear. After a while it’s gone I assume because of my filter. But there’s almost always that odd oil like stuff floating on top in the tanks. Does anyone have any ideas as to what it might be? I should add that my fish have never reacted poorly to a water change so it’s nothing immediately harmful. I can’t get a picture of it because it’s pretty see-through and doesn’t show up on the picture. If you’ve ever cleaned black diamond blasting sand and seen the oily film in the water, it looks a lot like that

Is the oil on the top like biofilm or protein film? Or is it something completely different?

It’s not like that because it doesn’t cover the entire top, it’s more like swirls

Okay guys, my new iphone was able to video the film on my water REALLY well so hopefully someone can tell me why my water does this and if it’s harmful. When I stir it with my finger it fizzles like a soda can.

Hi, hope all is well. I've had similar but I'm over in the UK England and have african cichlids.
I use prime and also API test kit.
Along with prime I also use a water conditioner called Easy life with added bacteria (30+ actions) Is a little cloudy when dosing but will soon clears.
Could possibly be a biofilm or protein as mentioned in previous post.

Is your water source near anything that could potentially contaminate your supply?
Is there adequate water flow.

There are a number of ways of helping..
1, wash hands before and re-rinse.
2, Agitate the water surface.
3, Use carbon as a polisher in last stages of filter. (I only use if need to and after any treatments).
4, Use a water conditioner with your prime.
Shoukd be on but Check to see if safe to use for your species of fish.
I have used water conditioner with prime and had no problems.
The haze Could also be bacteria bloom or well oxygenated water until settled.
I'd monitor situation.
This shouldn't be harmful to your fish unless really oily on top.

Does your water flow through or originate from a chalky area? My work place is on well water in a very chalky area, and the first glass of water out of a tap is always cloudy, which dissipates to similar to your video.

If this is the case, I’m told that it is very fine bubbles of carbon dioxide produced by the chalk breaking down in the water.
At work the water will clear from milky cloudy to almost completely clear within 30 seconds, and is completely clear within a minute.

It does completely clear in about that time. If I swirl it it clears faster. Maybe that’s the cause? We have since replaced the water heater tank because the hot water started coming out rusty, and the haze issue in this post is ~less~ but it’s still there. I have no idea where the water supply to my town originates or if the area is chalky or how to fix it though. Do you know if it’d be harmful?

I truly doubt it - we have several staff members living on site with fishtanks, all using the water straight from the taps! Nobody’s had any problems, and I don’t think they even use conditioner since there is no chlorine added! If anything, it should be great for any live plants as you have built-in Co2!
