So am I to assume Seachem?
"Let's hope you don't use water conditioner, plant fertiliser or any sort of medication if your fish get sick, then.
I'd avoid Stress Zyme simply on the basis of having a silly name.
In reply to Two Tank Amin, you don't know what's in Seachem Stability because they do not publicly disclose the species of bacteria used. So how can you say you don't want it in your tank? Can you name the bacteria that you do want there?"
But would you recommend it? I can not decide if it is worth adding every once in a while to aid my aquariums. Most people who actually use it seem to like it but it could be a misconception thats why I am asking
The general consensus among the most vocal members of this forum is that none of these sort of products work at all. There are many individual people, both here and elsewhere, who have said that they did seem to work for them. My own personal view: some of these products are better than others, Stability likely being among the better ones. Its bacteria are known to be stored in a spore state, which is what gives them a long shelf life, so ignore people shrieking that the bacteria must be dead because you can keep it for a long time.
I also think there is little value in adding these products once your filter has matured and cycled, as you have enough bacteria there already. Before maturation, maybe. If you do something to kill off the filter bacteria by accident, then again they could be useful. If someone says "these products are bad" then request them to present their data on why they think that, and make your own mind up.
