Kordon#31275 AmQuel Ammonia Control & Detoxifies Chloramine for Aquarium, 5-Gallon

Awesome.

WHY RISK KILLING YOUR FISH? READ OTHER REVIEWS HERE AND ELSEWHERE ON THE NET AND YOU WILL SEE THAT THIS KILLS!The alternative is doing fresh water changes and bring down your ammonia without the harsh chemicals. Improve filtration and don't take a chance... Hopefully I went through this so others wouldn't.Says in this ad that it does not remove oxygen from the water... BUT on the label it says that it can deplete the tank of Oxygen and to make sure that the tank is well aerated prior to using... Also in some ads states the product does not change the PH, but on the label it says that it "generally does not effect PH".Caused my ammonia to spike to super high levels and killed ALL my corals and inverts. Over $1K in live corals and inverts!I have tried to talk to Kordon (the company who makes the product) and they are in full denial.The stuff does stink & the aquarium water took on that same smell. I ended up having to completely empty the tank and start over from scratch and this was a fully cycled tank that has been up and running for over a year.NOT a good product. Like others have stated, use natural means when you can and use only what is absolutely necessary when using the chemicals...Also, I'm NOT a newbie... I have been an aquarium person since I was a kid... DON'T use this product!"
