I'm getting in some Blue Dream/Dreamy Blue shrimp tomorrow. My tank is a 7.5 gallon planted, which I am using the Neo DIY co2 kit with. I've noticed mold appearing on the diffuser. Is this mold dangerous to shrimp? Should I just remove the co2 from the tank all together? It isn't really doing anything for my plants so I am not apposed to getting rid of it, but just wanted to know I guess if the mold is toxic to shrimp.
