Oh dear lord.... yesterday... what is there to say... lady came in to get her water tested, and a girl that usually works register was my backup because we were busy. Lady says 'we've had 4 comet goldfish for a month and a half and somebody told us we were supposed to be doing water changes or something and to get our water tested'... That water test was the most ridiculous thing I have ever seen. Nitrates well over 200, off the chart. Nitrites over 10.0, well off the chart, CHLORINE was reading at 2.0...... Worst part, The girl who was working that's usually on register told her that 'she should do like a 25% water change because doing too much is bad, so only do 25% once a week until it goes down' and also 'you can clean your gravel with a gravel vac, but i think you should just take it all out and wash it'.... I've gotten in trouble a couple times for interrupting people with bad information and had to keep my mouth shut... i was in shock at the shades of purple on that test strip...
