My Tank Thread
I use one bottle per tank. Unless it's only a 20 gallon tank or smaller. Then I'd split it. Biospira has been working better than Tim's lately.Super helpful info thanks. I really like the sound of having a tank with a biofilter for QT as that greatly reduces the risks of ammonia.
Also I was looking at biospira and dr. tim's (I assume they are essentially the same thing). Do you add the entire contents to the QT tank? Or add enough to seed it and save the rest for the 2nd tank?
