I agree that the majority of it is new people who are doing their best to learn and adapt as they go through this experience. We are SOOOO fortunate today that we have a resource as valuable as the internet. Back in the early 90s when I first attempted saltwater, I had to rely on books, magazines, and LFS staff (the least effective) The biggest problem was, if you don't know the questions to ask, how do you know where to look for an answer? This lack of quality information sources led me to waste a LOT of money, kill a lot of unfortunate livestock, and ultimately give up on saltwater altogether.
As a family, we should be trying together as a team to help guide everyone through this process. We should be doing our best to help them understand not only how to fix their problem, but WHY they have it in the first place. An ounce of prevention beats a pound of cure methodology.
Personally I have a lot of sympathy for the newcomers to our shared passion. I am still relatively new to the reef side of aquarium keeping myself. I have had freshwater tanks for decades so I am a lot more resistant to those snap panic scenarios that other people, who don't have my experience, worry about.
I also agree that, while the new technology available to make reef keeping as automated as possible, does NOT make for a better reef. Diligence, patience, more diligence, and a WHOLE bucketfull more patience is what makes a reef great. Did nature build that reef in a day? We ALL want that beautiful tank we see in the videos. It doesn't happen fast. It takes years of hard work and sweat to recreate that. Save your money, LEARN the basics the way nature intended. trial, error, and hard work. You didn't jump on that first bicycle and ride off into the sunset.. you fell, got scraped knees and elbows, and tried again.
Let's all just remember, we all were that newbie once. There are no stupid questions. The only stupid question is the one never asked that kills a tank.
