This was very helpful actually, really appreciate your input Irene. Cory must be very happy to have you on staff :)

Other causes :
- A family member topped off the tank with seltzer water.
- A "friend" put "FIZZIES®" in your tank. (A childhood memory from another generation)
- The fish is named "Bubbles." :)

As always, thanks for the easily digestible science to help the community,

Hands down one of the most valuable videos I've ever watched.

This was SO helpful. I thought I messed up setting up my tank but #2 was the reason and I am so happy I didn’t mess up.

Great rare and important information. Thanks so much for this! It puts my mind at ease. I love it because it is a fast guide compared to Cory's live stream video in which you have to search for the nitty gritty. Don't get me wrong, Cory's talks are full of great information, but most of the time I don't want to sit through them every time I need the information I'm looking for. Cory should have hired you a long time ago! You are a gem!

Pearling on plants is one of the coolest sights in my tanks I love it. Makes me think the plants are happy XD

Great video, I get a lot of people asking me about bubbles too, now I can just point them to this video..
Another thing is microbubbles that are too small to float to the surface quickly so the water movement keeps them suspended and gives the tank a slightly cloudy appearance.
The way to tell the difference between bacterial cloudiness and suspended bubbles is bubbles are shiny, bacteria have a dull non reflective appearance.
No problem, its normal in this situation, actually its a good sign that you have full gas saturation.
I have that going on right now in one of my tanks, its a fairly newly set up 75g that has an overhead trickle filter/sump with a gravity drop(so there is no chance of a siphon) and very few fish, the water has so much air dissolved in it that these small bubbles don't dissolve.
When the tank is fully stocked these tiny bubbles will dissolve more quickly because the fish will be using more oxygen.

I'm currently aquascaping my new fish tank! I've finished with the hardscape and now I'm adding in the plants

Thank you for this video. I actually saw a video made in the past where Corey mentioned if you see foam on top you could have high ammonia. I’ve tried to find more information on that subject since. So happy to have a more in depth explanation. Thanks Irene and Aquarium Co-Op for all of this wonderful content!

Great video, thank u! Do you know anything about gas bubble disease? It has to do with an oversaturation of gases. Would love to see a video about it and how to treat it.

New fish owner. Newly installed tank. 2 female Panda Guppies. 2 Mystery Snails. First fill of 5.5 gl tank. No bubbler but Filter and heater(which were applied to tank last after 1st full fill and bubbles were already there before heater and filter were introduced. Your 2nd half of reason 2, 1:34, sounds exactly what I have; Millions of small bubbles over entire tank and plants and figures and sand. You say to keep an eye on it(which kinda makes me think it could be serious, just how you said it) but then said nothing about what to keep an eye out for or what to do if your keeping eye sees something that should be fixed or ignored. I hope you are still answering questions after 2 years of this video upload. I liked and subscribed. thanks to you or anyone in advance! oh fish and snails seem just fine. EDIT: I also poured the water in the tank in 5 mixing bowl fills(1 bowel also had a dose of of API Quickstart) cuz it was the largest thing in the house that i had and also poured it deliberately on the centerpiece which caused some splashing. I did this to avoid the fills from creating divots in my new evenly placed sand like stuff on the bottom.

I'm currently running a 20L nano shrimp tank, and I've completely planted in out. And only 3 shrimp. Even have a proper mini CO2 setup, and I can watch bubbles pearl out of my plants. It's so good to see

I used the Aquarium testing kit, ammonia etc, and my water is completely fine however, there's still lots of bubbles above the surface. Also, I wasn't putting any medication on my aquarium tank. I do a weekly 25 percent water change. The only thing I put on the water is water conditioner and stress coat. It seems like my fishes are doing well but I'm just worried about the bubbles above the surface. What do you think the cause of that? (I have a 10 gallon tank)

[STARPHASE]

All good to know! I turn my bubble wall off overnight, because my betta will surf it all night otherwise, and noticed that in the morning, there's often a small amount of little bubbles on the surface. It is a new tank, so that could be part of it as well. But I think the filter just doesn't break surface tension enough on its own. It hangs on the side, but it pretty low flow.

I also have live plants, so they could contribute as well.

Hi, I set up a new 10 gallon quarantine tank recently. I rinsed the gravels & all the media in the HOB filter. Since day 1 there has been a bubble film on the water, the whole surface. The water is clear, nothing showing. I can't figure out what is causing this. Also, he water parameters are fine.

This video helped my fishkeeping for the best 😊👍

[Jagdpantherl]

You can use dawn dish soap. ive used it for years and havent had any problems with it as long as you rinse it throughly. it is also enviromentally safe

3:39 when I see a slick on my main tank, I’ve found it’s usually a dead fish somewhere in there and I need to fish it out.

[neithermanc]

i was wondering about the "oil slick" on top of my water. thanks to this video i discovered out my own grubby paws were likely the culprit as i've been in there moving the scape around recently.
