Review: Fish Haven't Kicked the Bucket - This is good.. It gets rid of all the nasty chemicals like chlorine, chloramines, and heavy metals. I didn't really think about how dangerous those things were before using this product (oh well). It also claims to help your fish heal faster with some added vitamins. My fish seem fine, but they could just be tough as nails, who knows? It's pretty easy to use - you just add a capful to your tank and it works in seconds. I got the 8oz bottle and it's lasted me quite a while. It's definitely more convenient than trying to find fish-safe water elsewhere. Plus, my local grocery store doesn't even sell bottled spring water, what are they thinking? Anyway, overall, Tetra AquaSafe Plus is a decent product that does its job (I think). My fish haven't died yet so I guess it works!
Review: Great pro.\nDuct , great price and never won damaged one of my fish - Great product, truly, the only product on the market.You can 100% trust to set up your tank to remove any poisonous chemicals coming from the faucet.\nGreat protection for the fish against toxicities

## Questions & Answers

**Q: Is the product supposed to have a seal?**
A: This product never had a seal. Even if you buy it from a store or here. Tetra just never did a seal for this product!

**Q: Does this remove ammonia? I just put in safe start.**
A: Not directly... Safe Start introduces Nitrifying bacteria into your tank environment... Turn off uv sterilization when adding.  The bacteria convert ammonia to nitrite and other bacteria convert nitrite to nitrate.  All are toxic to fish to some degree... Ammonia being the worst and becomes deadly at about 8 parts per million (it burns the gill membranes)... nitrite at about 40-80 ppm and nitrate at about 160ppm... Water changes remove the nitrate... Seachem Prime is excellent for detoxifying all three and for removing heavy metals from your tap water in addition to dechlorinating... But SeaChem Prime does not remove it either... It binds the toxic molecules thereby making the water "safe" for fish and giving the bacteria colonies a longer amount of time to break down the toxins....Overcrowding your tanks is the major source of excess ammonia...

**Q: Does this expire?**
A: Yes, chemicals do expire and each one has an expiration date stamped on the bottom of the bottle. Shelf life is three years.

**Q: does aquasafe plus conditioner clear new tank with added fijji pink sand cloudiness? If not what  does?**
A: You want an anti-flocculant such as Tetra Water Clarifier or SeaChem Clarify. It makes all the little pieces stick together making them bigger pieces and easier for your filter to catch
It'll look worse before it gets better but will clear faster than just waiting. Like anything added to a tank, measure the dose and don't free pour
