so ive noticed the last few days im getting what looks like micro bubbles staying on the top of my water in my sump and also see some bubbles on the sand bed now. in the sump the other day i noticed the bubbles so i stirred the water to break up the bubbles when i did this i noticed it was slimmy and looked like snot. so my question is what is this? and what do i do. i started dosing mb7 like 2 weeks ago also running bio pelllets. thanks everyone.
