I have scrubbies in my sump , i've had them for a while now , before because i've read that they are good bio media with lots of surface area. But now I'm thinking if they'll be able to handle bio load of keeping rays?
Also started using Pumice instead of ceramic rings.
I'm just thinking if it will be ok to keep on using the scrubbies? or should i change them to something else.
