Hi! I am currently raising a bunch of baby axolotls and have started working ahead so I am prepared. I set up a 10 gal tank and have been letting it sit with the filter just to see how it runs for a few days (not cycling, nothing has been added except prime) and this weird stuff as been forming at the bottom. it’s almost like sand and it’s not changing the water at all. I am confused what it could be and if it will maybe cause problems once the guys get big enough to go in there, I attached pictures. Thank u for your help!!
