Removes chlorine, chloramine, and ammonia
Detoxifies nitrite and nitrate
Highly concentrated
Marine and freshwater

Safe is the complete and concentrated dry conditioner for both fresh and salt water. Safe removes chlorine, chloramine and ammonia. Safe converts ammonia into a safe, non-toxic form that is readily removed by the tank’s biofilter. Safe may be used during tank cycling to alleviate ammonia/nitrite toxicity. Safe detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them.

This is highly concentrated!

Use 200 mg Safe (scoop) per each 200 L (50 gallons) as needed to reduce chlorine and chloramine or per 50 L (13 gallons) for ammonia.

I switched from liquid dechlorinators to this concentrated powder and one container lasts forever. It handles both chlorine and ammonia in my planted tank without any fish stress.

Chloe D. ★★★★★ Oct 18, 2026

This tiny scoop of powder treats way more water than the liquid stuff I used to buy, and it’s been a game changer for my 75-gallon tank. Tested the tap water after a water change and both chlorine and ammonia read zero.

Adam E. ★★★★☆ Oct 21, 2026

I've been using this for a few weeks now and it really handles the ammonia in my new tank setup without any issues. The powder formula is super concentrated so a little goes a long way, which makes the bottle last months. Only wish the scoop were a bit easier to find in the bag.
