Python Multi Purpose Bio-Support Aquarium Water Care

It's hard to say how well these bacterial products work. None of them instantly cycle or allow you to add a tankful of fish all at once, no matter what the labels say. I've tested and found moderate to high ammonia readings testing most of them. The worst were Microlift products, but even Seachem Stability, API Quick start, as well as others all tested for significant ammonia. That said this is the only product I've tested that didn't contain significant amounts of ammonia. Meaning I can't say for sure that it was a bottle of live bacteria, but it wasn't a bottle of dead bacteria. I suggest everyone using these bacterial products test for ammonia before adding to your tank. I add 2 drops of the product to the test tube ( I use the API liquid reagent test kit ) and add conditioned tap water to the fill line, then add the ammonia test liquids, shake and wait. If you find ammonia, you've most likely got a bottle of dead bacteria. It may harm more than help your tank. I've found calling the companies that make the products universally unhelpful. Obviously it doesn't matter as much if you cycle WITHOUT FISH, but add ammonia to tanks of fish at your own risk. Actually you probably shouldn't do that.
