I know you agree
The lids of my fishtanks(seemed to have originated from the goldfish tank) recently became infested with flies, covered in little whitish flies that now flies that fly everywhere(found some in my bedroom), And i want to get rid of them, they look gross and seem unsanitary.
last week I did a 50% watter change in both tanks and bleached the lids, unfortunately the flies have returned i haven't ever heard of this before and need ideas to kill them

Thankyou
