Hi, any old reefers here? I mean any people that keep reef tanks when it’s not cool? Like back in year 1900 (I’m dumb with numbers) ?. I’m really curious about the history of saltwater keeping, how it’s like back in the day, or how technology improve making the hobby easier, and what technology used in the hobby changes the most. Is it impossible to keep corals back in the day?. How is maintenance done back in the day? Do they actually use table salt? Is using table salt even possible? What are the most popular corals back in the day.
