Wow! That is a bad
cyano outbreak. I agree with going the natural route first. Scrape, siphon, change water, more flow, etc, etc. My one experience with
cyano was after a fish sitter overfed a year ago. I upon returning home I fed every other day and did lights out. I increased flow, went from 1 - 10% water change a week to 4 - 5% changes and siphoned the stupid stuff with every water change. No matter what I did the vile stuff just kept coming back. After several weeks I finally resorted to using the chemical stuff.
IMO, because I had already addressed the root cause it went away after 1 treatment and has never returned. Maybe another week of siphoning etc would have solved it.
If I get another outbreak I will do the same thing, go the natural route and only resort to chemicals after several weeks.
BB tanks are easier to maintain as you can see the
detritus and it is easy to siphon out. They are not more effective. I use
BB in my
QT tank. I prefer a
DSB otherwise.
