I went to Cozumel and Playa Del Carmen for 6 days. My sister fed 3 times. I did trial runs weeks before. Skimmed real dry, ato become double the size, fed once every other day, started changing water every other week. Preparation and all is great. My phosphates rose but that's cause the reactor needed a tap, stupid maxi jets. Next vacation 2 weeks.
Screw a tank, I'm no slave! not to this not to anything. Live people. If your paranoid get a freaking ip camera and an apex. Besides feedings my tank can go un manned for 3 weeks no problem. Glass would be gross though.
