When i first started my sump my ceramic rings were all brand new and white. As time went by tiny little brown specs started to appear on each ring. Over the weeks and months these hundreds and hundreds of specs gradually grew until they were all little brown clumps. Now i thought, great, these specs are my bacteria.
However, when i rinsed out my bio media the other night (it was getting clogged up), all the brown clumps were washed away and my rings looked very clean again. I thought, oh dear, i've just got rid of all my BB. Anyway, i got my tank up and running again, checking my parameters daily since, and they're fine. So, i was thinking. Are the actual BB invisible and the masses of brown clumps i saw on my rings were in actual fact just crap!!
