Hello reefers, so I have a Red Sea Max E-170 (about 40 gallons worth) and it felt like a full on job today. From making just 10 gallons of RODI to mixing the salt, testing, waiting on it to heat, changing water, putting things up and feeding took me a lot longer than I wanted and it wasn't even a detailed maintenance day. Wouldn't say I would give it up because I love this hobby but curious to see what others do for the love of their tank...I'm probably at least 6 hours every week!
