My fun one from today. Lady comes over with a bottle of Stress-coat in her hands. Asks for the other stuff that goes with it. I ask the name and she says she doesn't remember. I ask what color is the bottle, she can't remember. It's that brown stuff that you put in with Stress coat to get rid of water impurities and we are the only ones that sell it. I start mentioning different brands to which the reply is always no. She starts getting mad because I don't know the name of something that she has no clue of. I mention that the Stresscoat is a water conditioner an removes chlorines a chloramines. She replies that it isn't enough. Her fish alm ost died without it and with it has kept her carnival goldfish, who is about 6-7 inches going by her measurements, alive for 7 years in a 10 gallon tank. At this point I just had to walk away. But if anybody knows what this wonder chemical is, please let me know. I have a 29 just begging for a pacu.
