What benefits have you noticed after adding ceramic biomedia or sintered glass like siporax to the sump? Did it help with carbon dosing?

By ceramic biomedia I intend the plain ones without any embedded sulphur:

• Maxspect nano tech bio spheres/blocks
• Brightwell Aquatics Xport BIO Dimpled Brick

Thanks!

I used both Brightwell stuff and siporax( in a smaller tank).
I took most of it out as my Nitrates hit 0 and I had to start dosing it.
It is definitely double edge sword and it can also be a nitrate factory if detritus is accumulated.
Larger Bio Bricks can apparently help with denitrification too and it seemingly happened in my larger tank. If you don't have large amount of quality, porous Live rock it is the way to go though.
