White stuff from my return pump after powering back on?

[Jereli]

So I have been researching around and can't seem to find an answer. Everyone I turn my return pump off for my water changes it blasts a bunch of white things from the return line.i can not identify this but my yellow tang eats it. Its kind of hard to describe it. it just appears to float aroundand always happens when I re apply power to my return pump when I do my pwc. Any ideas what this can be?

If it tastes good to a fish, it can't be too bad. Be curious, but I wouldn't worry about it. Likely just old food or other organic matter that accumulates when the power to the pump is turned off. Doens't last long, right?

same thing happens to me and i always thought it was air bubbles

 

[Jereli]

Oh No its just a blast at the start.it doesn't keep coming out...its definitely not air bubbles though looks more meaty. iam not worried about as its not doing anything bad but just curious if anyone knew what this was since isee it everytime I apply power again
