Over the past week I have had white stuff appear on my tank walls. Its not long streaks or small spots but irregular shaped deposits

At first I thought it was deteriorating flaked food, but that doesn't seem to be it. I scrubbed it off but more appeared within 24 hours. Water quality seems to be fine. Fish seem healthy too (guppies, cories, and otos), so I don't see any signs of ick.

I was wondering if it could be egg deposits from my assassin snails?

Any ideas

The photo didn't load. Can you repost it? How long has your tank been set up? Sometimes different kinds of 'stuff' (fungi, algae) grows in tanks. My mystery snails leave slime on the walls of my tank I can see when I do water changes. I'm always wiping that stuff off!

Picture is pretty blurry in closeup so hard to say what that is. What are your nitrates reading?

Just did a set of tests

Nitrates are 40ppm -- but they always have been that in my setup
Nitrites are 0ppm
Ammonia is 0ppm
pH is 7.0

Do they move around when you watch em? Did u try to remove with your finger? Is it mushy or hard? Calcium deposits possibly?

The don't move. They rub off easily with my finger and don't feel gritty

Must have been the case as I did another cleaning with my spongy brush and it hasn't come back
