Some People Clean Algae, I Clean Critters

[MarkoD]

every single day when i wake up my glass is covered in little critters. i've identified hydroid jellyfish and copepods but there's other little bugs as well.
my water is littered with these things and they're floating all over my tank

anyway to lower the population of these things, i want my water and glass to look clear and not like its constantly snowing
