Fish Crazy
any one use these.... recommend?
I have one but dont run it 24/7. I run mine on my QT or when I have sick fish. They do help remove pathogens from the water and lots of people have them running on their tank constantly.
Some people will say that it kills off the benifical things in the water as well but I personally think the benifits outweigh any potential cons (even though I dont run mine 24/7).
Wouldnt say it is essential but is a useful piece of kit to have around even if you only use it for emergencies.
