So first off, I've been keeping reef tanks since 2009-ish. So admittedly, I'm an old curmudgeon. That being said, besides keeping our pets happy and healthy, the best thing we can do for this hobby is help it grow so even more people can learn and improve on it. Not more than 3 years ago I remember Hanna Alkalinity Reagent being $9.00. It's now $15.00. I remember Ecotech Versas being $149.99, they're now $209.99. This hobby is inherently tough and expensive, and it should be. We're keeping tropical animals who live underwater in our living rooms. I understand COVID-19 happened and inflation, but eggs and milk haven't gone up 67% like Hanna Alkalinity Reagent, or 40% like Ecotech Versas. This hobby is difficult enough. Is it just me or are companies price gouging to the point of it being unsustainable?
