Bubbling toilet - Do i have a septic issue?

Hi all, question for the plumbing types!

So my daughter flushed the toilet today and it started to bubble (clear water/bubbles)

Some info

-I am on a septic
-It stopped, and has not bubbled again on several subsequent flushes
-I half filled the tub and let it go (no bubbles)
-I can hear water flowing through the pipes where they exit from the house to the septic (basement wall)

I am most concerned that this is a septic issue. Do you believe that is so? Could it possibly have been a partial blockage in the toilet drain pipe itself, which has subsequently cleared?

Thanks

I am not on a septic system and I have seen my toliet bubble. Have checked to see if the vent pipe was blocked. Sounds like it was equalizing pressure in the system.

All in service septic tanks produce gas due to the anaerobic decomposition of organic matter. If that gas is coming out of your toilet it is likely something related to vents and/or trap.

If it was coming from the tank it would stink.

Just sucks if it backs up...

I did pull the lids off the tanks to see what I could see.

First tank - When a toilet flushed I could see the water going in, with a slight drop down to the liquid in the tank. That is good I presume. There was solid visible (not sure how much solid I should be ale to see?)

Second tank was all liquid. No solids at all. That is all good I presume.

Im going to keep a close eye on it over the next 6 weeks or so and when the ground thaws out have it pumped. If any other digging is required due to a problem....well, its hard as rock right now.

Old well driller always told us if you open your tank throw a dead coon or cat in the tank .it will pick start good bacteria growth in your tank. Cleaning products can kill all the good bacteria growth in your tank.

My pumper outer said to throw any "un edible" meat as well.

"Air Behind Water" Make sure your venting for the stack is not plugged with a nest, rodents or snow.
