White flakes in aquarium? Need help identifying

[SageTheKeeper]

So I’ve had this pool/pond for about 2 months and about a week ago these “heavier flakes” started appearing. They sink right to the bottom. It appears they come out of my filter(55 gallon drum with lots of sponges) but not positive. I had a couple fish die since it started coming around. It’s a freshwater pool with with 45 mil pond liner sitting at 77°F

Looks like bits of old moldy flakes and other debris?

not flakes were used and these are hard as a rock so I’m not sure

could it be calcium flakes? i get some out of the vinyl tubing of my returns when i shut down and back on for water changes.

That’s my thought, that’s really the only thing I could find it could be

Are you using warm/hot water when you do water changes? The reason I ask is that older water heater tanks or ones that haven't been flushed regularly can have these type of deposits in the tanks or the anode rod is starting to fail.

Are you seeing similar crusty debris when dispensing hot tap water into a drinking glass or noticed plugged faucet or shower aerators?

I was using warm water and my water heater is new as of November 22 2022. But I am almost certain it is a calcium build up cause my heaters have a lot of it built up on them.

just found this on a 1 month old heater as well appears to be the same stuff

Agree with Deeda, home water heaters often produce, and have this flaky material come off.
The hostile environment inside heaters with constant cold water, hot water fluctuation in and out, is not a stabile environment.
I used to need to drain about a quart viscous liquid off the bottom of my home water heater about twice per year, from that valve located near the bottom of the unit.
Minerals in water often precipitate out due to the opposing forces of heat/cold.
If I didn't;drain that viscous stuff off, I would often see white flakes appear in the aquarium, and......
The buildup of viscous stuff would lessen the efficiency of the water heater itself.

This thread is like home learning and fish combined… I love it lol. Thank you
