"A MUST BUY!"Use a heater and crank it to 82 degrees again without fish in the tank. It is just as good when compared to other brands of conditioner. Dealing with biological cloudiness in my tank for some time. More doesn't hurt anything, but it's just wasted. If you have new tank syndrome then this is the stuff. I have a 5 gallon tank, so that number was waaaay too high for me. Beats the heck out of those expensive suit cleaners.

"Mostly for betta's."My water is crystal clear again, and it smells like a healthy fish tank again. I recieved it today at 3pm and applied it around 4pm. Boy, I thought I was having trouble with my filter. It only requires 3 drops per gallon you add to your tank. Crystal clear after changing water and adding this to my 2. You have to understand when to use this product, and what is is used for. This product is exactly what it says it is.

"I was very surprised."From their own colon or a hole in the ground. If you're serious about fish keeping, always quarantine and always use Stress Coat! 4-5 squirts in a sink of water, soak my suit 10 min, wring out and hang to dry. The top is a measuring tool as well which I was not expecting. I read the reviews, and decided to give this a try. It has been 4 days and our beta is loving the clearer water. No exaggeration-- literally cleared overnight.

I do not use this as a product to treat my tap water. We use it when we clean& change out water. Fish would die occassionally every few weeks or so. I even poured in extra to help with the healing.

"I have guppies."I tried it without the water change and really didn't make a difference. It is much safer to simply to add 3 drops per gallon. The chloramines contain a small amount of ammonia. I'm sold on this, I've tried SO MANY and wow. Use a heater and crank it to 82 degrees again without fish in the tank. Use a heater and crank it to 82 degrees again without fish in the tank.
