are you really recommending using a product called "Stress Zyme"? have you read the msds?

Yes, and if you read it it says:

HAZARD
Not hazardous

It has a rating of:
Flammability = 0
Toxicity = 0
Body Contact = 0
Reactivity Chronic = 0
Everything else in the msds is standard boiler plate cya verbiage that is in every msds.

If you are reading something else in there, let me know.

ACUTE HEALTH EFFECTS
SWALLOWED
? The material has NOT been classified by EC Directives or other classification systems as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence. The material may still be damaging to the health of the individual, following ingestion, especially where pre-existing organ (eg. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.

EYE
? Although the liquid is not thought to be an irritant (as classified by EC Directives), direct contact with the eye may produce transient discomfort characterised by tearing or conjunctival redness (as with windburn).

SKIN
? The material is not thought to produce adverse health effects or skin irritation following contact (as classified by EC Directives using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.

INHALED
? The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified by EC Directives using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.

CHRONIC HEALTH EFFECTS
STRESS ZYME Section 11 - TOXICOLOGICAL INFORMATION
? Long-term exposure to the product is not thought to produce chronic effects adverse to the health (as classified by EC Directives using animal models); nevertheless exposure by all routes should be minimised as a matter of course.

TOXICITY AND IRRITATION
? Not available. Refer to individual constituents.
As far as bacteria showing up on there own, this product helps them show up and by using it the water is much clearer and the fish waste solids do not accumulate in the bottom of the fish tank as they do if I don't use it.
