Its says it helps clean a dirty aquarium but i see nothing at all this is a boo boo product! Its suppose to eliminate ammmonia and nitraite and keep the tanks clean but i see the water is yellowish green. i ended up have to clean the tank out more times then i use to using another product.

Pros: no pros..

Cons: not effective

I recommend stress zyme to anyone who is setting up an aquarium. It is a good bacteria starter, however I still recommend allowing the aquarium to set up for at least 1 week before adding fish.

Pros: good bacteria starter

Cons: none

Stress Zyme works great for setting up a new aquarium by providing the beneficial bacteria needed to help break down waste.

Pros: helps boost benefical bacteria in new tanks

Cons: none

STress zyme soothes the bodies and fins of my fish
after adding new fish or after cleaning the tank.
I believe it actually saves fish by balancing the water in the tank.

Pros: not expensive

Cons: none

This is a great product when you are setting up a tank. It helps to get the good bacteria set up in new tanks and allows you to add fish faster.

Pros: Gives a boost to new systems

Cons: would be great if was combined with stress coat.
