pot scrubbies in sump

can they be submerged or do they need to be treated like bio balls and be kept with a trickle?

I believe that they are more efficient in a trickle but will still get the job done submerged. I have bio balls on trickle and then scrubbers in the bottom of the sump. I hope this helps. I have read that there are 2 different types of bacteria and the type that grows in an oxygenated environment removes more ammonia and nitrites. Don't quote me on this I'm not a scientist.

The conventional wisdom is that scrubbies are best not submerged. If you want to submerge your bio media, there's other media (like seachem matrix) which will be better.

Thanks for the help. You both confirmed what I was thinking.
