Knowing that I’m setting up a new 180 gallon tank, I admit to slacking-off on my current tank. Now there is a bad Cyanobacteria outbreak. I would never just use ‘Cyno-rock’ “as-is” to jump start the cycle in my new tank, by putting it into the new DT, but could I scrub the Cyno-rock with a brush in a bucket of saltwater (to preserve the beneficial bacteria) and use it in a dark sump under the new tank? I hope my question makes sense. Thanks.
