Reoccurring flakes

[Axolotl52]

Ever since my axolotl had her first fungus infection I've noticed these constant flakes appearing on the bottom of the tank. It seems to clog up both the sponge filter and power filter. At first I thought this may have been broken down detritus but I've rinsed out both the power filter media and the sponge filter and it comes out as brown in the bucket but within a day its back filling up the bottom of the tank. Water is fully cycled ammonia 0, nitrite 0, nitrate around 1-2 ppm(just hardly showing color on the water test), PH is 7.5. If anyone has any idea of what this could be please let me know, maybe I'm just paranoid or not rinsing the filters well enough? I've included pictures below. Only one axolotl is in the tank and any waste is immediately cleaned up as soon as its seen, doesn't seem to bother her at all. Tail and gills aren't curled and she still eats perfectly fine.

They look something I regularly get. I believe they are precipitate from hard water at it dries at the top of the tank and falls in. Do you notice a lot of white chunks on areas that have been previously wet?

I find I get less of it if I keep my water level topped off.

That was another thing that was on my mind, and i'm pretty sure you're right. I have noticed the white gunk builds up quite fast, especially on the water line, I try usually to give it a wipe with a sponge at least once a day and use the scraper for the more stuck on parts. I think the main problem was vacuuming the flakes first then moving the hides around to look for any messes to clean up which would kick up any flakes on top and then settling back to the ground an hour later, thank you for the help.
