@GaryE posed the topic of superstitions. I now ask, what are the really dumb things you used to do and cringe at now ?
Mine is when I was starting out I would clean my 5 gallon aquarium every week. Not just a water change but really clean it. I put the fish in a gallon jar and took my little aquarium to the bath tub and rinsed it out good until the gravel was running clean. Rinsed out my box filter and put brand new filter floss and charcoal in it and then took it back and refilled it with clean non-de chlorinated water straight from the tap. You don't buy Jungle Start Right on a 25 cent a week allowance. Fish went back in and I was happy until the next week. How did I not kill more fish ?
