My LFS guy tells me that these are great in the beginning but after a while the bacteria in the Marine Pure becomes toxic. He tells me also that he miracle mud also becomes toxic, like a sand bed that doesn’t get stirred. Any validity here? I’ve had a box of the spheres in my sump for about 3 months and same with the miracle mud. I do trust my LFS but he’s a bit of an old school purist.
Sometimes easiest solutions are the best! I presume no one has any serious problems with this approach? a little detritus below and easy enough to address. So easy > I like it!
