It's funny ... lately I've been comparing how I handle my aquarium now compared to when I was back in 8th grade. I pretty much floated my fancy goldfish for 15 minutes, not much acclimation, dumped tap water right into the tank and did a "thorough" filter cleaning every couple of months. QT? What was that?
So I've asked myself, what's changed? Many members that had tanks years ago, took a hiatus and recently returned usually say how much things have changed. But has anything really changed? Filters, I assume are better, heaters are probably more efficient, lights are probably brighter ... so basically the equipment used has improved, but still functions the same way.
The fundamentals hasn't. Cycling hasn't changed, beneficial bacteria back then are the same as today. Stocking hasn't changed, putting a 10 inch oscar in a 20 inch tank isn't as good an idea today as years ago. So, what's really changed? The more I think about it, the only thing that's really changed is how quick and easily information is available ... in other words, the web.
Years ago, we knew what we were told by an LFS
employee or a friend / relative that "kept" a fish tank .. the back in the day version of research. I can tell you first hand when I think back to those who I knew had fish, how those fish survived is beyond me. Bala's in 20gal tanks, 8 common goldfish in a 10gal etc etc etc. Back then it was what we knew, today we should know better ... because we should research research research.
Just my two cents worth.
