DECHLORINATOR: Removes chlorine, chloramines, heavy metals which are found in tap water and can cause gill and tissue damage, breathing difficulty, stress and fish death
AMMONIA REMOVER: Removes the toxic ammonia continually released by fish through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish

Clear the tank
Works great but still takes a few days to clear up water to a crystal clear look. Priced rights and is fine in my 10 gal tank.

Helps balance your tank.
Started using this on a friends recommendation. He has a clear clean 40 gallon tank with three large gold fish.

The only water conditioner you should buy. 5x more than others.
The best water conditioner money can buy. Not only does it condition the water it eliminates ammonia nitrate and nitrites all of the compounds harmful to your fish. You also get 5 times the amount of other water conditioners. Because itâs so concentrated you only need 1 ml as opposed to 5 ml of many other conditioners. This means it will last much longer.

Reliable Water Conditioner with Minor Packaging Flaws
This water conditioner works really well and quickly removes chlorine and detoxifies my aquarium water. Itâs a reliable product that keeps my fish safe and healthy. The only downside is the bottle can be a little hard to control when pouring, which leads to small spills.

Must have for any fish keeping enthusiasts
This is seriously a must buy for any fish keeping enthusiasts. Whether you are starting a new tank or simply just doing a water change unless youâve got fancy water you absolutely need this. And for the price it last a very long time. I use this bottle on both my 20 and 40 gallon tanks and itâs lasted me about 8 months so far with a quarter of the bottle left. Doesnât muddy up water or anything and they are easy to store especially with a lot of stands having built in shelves. Doesnât seem to throw parameters off.
