Not sure where to post this but I noticed some white fuzzy stuff on my heater... Is it maybe BB?? I know the shrimp that I did a fishless cycle on had some white fuzz but idk if this is the same.. Also the glass has some white looking spots ??? What do u guys think ?? It's stocked with 7 rummynose and I'm doing frequent PWC. Any ideas ??? For some reason it won't let me post pictures
